Plein Air das Album, sind Aufnahmen eines maßgeschneiderten Instruments, einem „Pflanzen-Synthesizer“. Von unseren Ohren nicht hörbare physikalische sowie biochemische Reaktionen einheimischer Laubbäume, genauer einzelner Blätter, werden über Lautsprecher hörbar. Sensoren aus der naturwissenschaftlichen Forschung wandeln Datenströme aus Photosynthese, Messungen von Temperatur, dem CO2/Kohlendioxid Laubbaum-Feuchtigkeitsaustausches verschiedener Blatttexturen, sowie Lichtflussdichte um in sich stetig verändernde „data sonification music“. Die unbeschreibliche Klangfülle dieser computergenerierter Musik eines „Pflanzen-Synthesizers“ wird beeinflusst von der jeweilige Raumakustik, Umgebungstemperatur, Raumklima, sowie im live set-up von der Anzahl der im Raum anwesenden Zuhörer, aber auch wie gesund, gestresst, ermüdet die Pflanze ist, in welcher jahreszeitlichen Wachstumsphase sich das Bäumchen befindet, wie achtsam es gepflegt, mit Wasser, Nährstoffen und Tageslicht versorgt wird.


Seite 1: Insgesamt sechsundzwanzig Minuten, besteht aus 4 kürzen Aufnahmen, Laub schottischer Erle, Eiche, Holunder & Birke. Die Aufnahmen wurden in einem der historischen Gewächshäuser des Botanischen Gartens Glasgow 2017 gemacht. Sehr dramatische Lichtwechsel im Juni, intensive Sonne, schnell wechselnde Wolkenformationen, machen diese Klangstrukturen zu einem dynamischen, intensiven Hörerlebnis, kraftvoll wie ich mir einen Tornado vorstelle.


Seite 2: Fünfundzwanzig Minuten aus dem Baumklang-Studien-Zimmer Köln, 2015, einem Raum ohne dramatische Lichtwechsel, erinnert diese Aufnahme eines Birnbaum-Blatts an Minimal-Music, die zum Eintauchen in diese Klangwelt einladen. Dieses Hörstudienzimmer ist seit 2008 ein künstlerisch-wissenschaftliches Forschungsprojekt über das Hörbar machen von Pflanzenklängen.

Robert Barry | The Wire Magazine (The Wire 429)
The photo on the innersleeve shows the interior of a glass domed building. In the centre sit two young trees in big black plant pots. They are surrounded by equipment stands, wires snaking from the leaves to the ground and up to a chipboard box. A pair of human legs, with what looks like a computer keyboard resting on their lap, extend from beneath the box to the floor. If the image conjures up some bizarre plant-machine-human hybrid straight out of the pages of a Donna Haraway manifesto, the truth is not far off. All the bulbous electronic bloops and clattery percussive slashes on Plein Air are derived from realtime data on the photosynthesis and transpiration rates of different plants. Must be one of the few shows where the band get their instruments from a tree nursery.


Tim Collins and Reiko Goto first conceived of the project in Duke Forest, North Carolina. While visiting the Duke University Teaching and Research Laboratory there, the artists assisted a team of scientists measuring the reactions of the trees to carbon dioxide levels. From a forty-foot tall structure, they set up sensors and took measurements. And then a cloud passed momentarily in front of the sun. Immediately the sap rose, photosynthesis rates went up. It was the speed of the reaction, that sense of living immediacy, that proved such a revelation. They set out to “hear the tree” and enlisted Scottish programmer and software developer Chris Malcolm to help them realise the project.


Plein Air the album collects two live performances from Collins, Goto and Malcolm’s bio-acoustic set-up. The first recorded in the botanic gardens in Glasgow (the glass domed structure on the innersleeve) in 2017 and the second, a single 25-minute track drawn from a heritage pear tree, was produced in a small office in Cologne in 2015. Producer Georg Dietzler points out that the weather was calmer that day and, reflecting this, it’s a mellower, more minimal and repetitive take. On side A, however, under Scotland’s uncertain skies, the sound is as wild and untamed as nature itself.


A ten years project by Tim Collins, Reiko Goto and Chris Malcolm culminates on ‚Plein Air | Silva Datum Musica‘.
By nature, experimental music is defined by singular, radical thinking. It is a push, joining ideas and sound, toward the unknown and unheard. Yet, setting the ambitions of this remarkable creative context aside, it remains rare to encounter objects which veer so far from the beaten path that they feel like their own quiet revolution of one – challenging the very conceptions of music, as the architects of the avant-garde once did. This, in the simplest terms, is what Plein Air | Silva Datum Musica, the culmination of a ten year project by Tim Collins, Reiko Goto, and Chris Malcolm, has seemingly managed to do. Comprised of recordings made on a custom built, plant-driven synthesizer, issued by the German imprint Gruenrekorder – it is an extension of their long standing dedication to musical and sound-art efforts built from field recordings, a stunningly beautiful and radical rethinking of the base notions of organized sound.


Encountering three artists joining forces, driven into new realms by interfaces with technology and chance, Plein Air | Silva Datum Musica is one of those rare LPs which can instill even the most weathered experimental music fan with faith. There is still ground to be broken and adventures to be had. Created with a custom built, plant-driven synthesizer which uses scientific sensors and software programming to generate real-time tree leaf data. Light, photosynthesis and transpiration modifies sound, giving way to electronic rhythm, melody, texture, and harmonic shifts, directly linked to atmospheric conditions and a tree’s response.


Stunningly beautiful, rich, and challenging for its raw sounds and ideas alone, Collins, Goto and Malcolm’s Plein Air | Silva Datum Musica is made that much more compelling by the perceptible absence of ego of its creator’s hands – an engrossing work of unadulterated, abstract sound – at once calling to mind the efforts of the mid-20th century orchestra and synthesis based avant-gardes, while delving toward the future entirely on its own. It would be hard for us to recommend this one enough.
Issued by Gruenrekorder on vinyl in a strictly limited edition of 300 copies, so don’t sleep. It’s not going sit around for long.


Only on Gruenrekorder, it seems, would a release appear claiming to present “recordings from a plant-driven synthesizer” and focusing on “plant bioacoustics.” The German label has a reputation for bringing unusual projects into the world, and its dedication to the strange and fascinating is one of the things to admire most about the imprint. This latest outing (issued in an LP edition of 300) certainly qualifies as different: to record the material, Tim Collins and Reiko Goto worked with a custom-built instrument that uses software programming by Chris Malcom and scientific sensors to produce “real-time tree leaf data.” Said device transcribes into sound form (data-sonification, in other words) the ‘music‘ produced by leaves, material whose timbre and volume are determined not only by the specific tree type but also conditions in the immediate environment such as temperature, light, carbon dioxide, and humidity.


Photos of the instrument setup show it to be an easel-styled construction that instantly establishes a through-line to visual artists such as Van Gogh and Monet who transcribed the outdoors into painted form. The Plein Air collaborators differ from open air painters, however, in that their generative sound recordings are facilitated using software. As described by Collins and Goto, the project isn’t only about sound content; there’s an ethical dimension in play, too. One of their goals involves exploring the empathic interrelationship between humans and trees and more generally the relationships of people-plant and culture-nature. If we’re presented with evidence of a tree as a live entity, how, they ask, does our sense of moral duty change towards it, especially when the nature object has historically been regarded as property, utilitarian resource, and non-sentient.


Adding to the recording’s appeal, the opening side’s four pieces were recorded in Glasgow under different conditions than the flip’s side-long setting, produced in Cologne. The Glasgow recordings were made at a curved, Victorian-era glasshouse, which allowed fluctuating weather conditions to influence the dynamic range of the sounds produced; a sheltered, quiet office room with one window was the setting for the Cologne piece, which is more soothing and less characterized by change than the others. In short, anyone who thinks one tree sound is the same as the next need only compare the two halves to conclude otherwise.


Each track on the Glasgow side was generated using a different leaf, namely Scottish Elder, Oak, Elderberry, and Birch. “Alder” features lurching, vaguely dissonant melodic meanderings and percussive punctuations resounding amidst a backdrop of soft, industrial-styled textures. In some strange way, the slow, meditative result doesn’t sound completely unlike the sound of an improvising raga ensemble with harmonium and percussion as the main instruments. The intensity level increases in “Oak,” with this time the melodic material rising and the overall tonality of the material dark and aggressive compared to the opener. The sound mass creaks and groans with forceful intent, the track’s stepwise dissonances disturbing, its mood nightmarish. “Birch” concludes the macabre, unsettling first half with nine minutes of intense melodic flurries, percussive batterings, and siren-like howls.


In the twenty-five minute “Pear,” whose sounds were sourced from a regional heritage pear tree leaf, the timbre of the primary melodic element shifts from harmonium or organ to high-pitched, warbling synthesizer; in fact, the sound details on the side are all brighter than those on the first. Stylistically, however, the second side shares with it the explorative feel of an improvising group birthing a meditative, slowly evolving drone in real-time. With the ringing of a tambourine, the bass pulse of a hand drum, and the shimmer of a tamboura all part of the sound design, the image of an Indian ensemble performing live is again evoked. As producer Georg Dietzler correctly notes, the recording is invaluable for bringing the listener “face-to-face with the sound of the breathing of a tree.” We’ve all seen, felt, and even climbed them, but we’ve probably never heard them before in the way they’re presented here.


TJ Norris | Toneshift
With each names for trees, this latest collaboration between Tim Collins, Reiko Goto, Chris Malcolm (here as Silva Datum Musica) is a unique journey into the great outdoors via a custom-built plant-driven synthesizer – you heard that right. An instrument that “uses scientific sensors and software programming to generate real-time tree leaf data. Light, photosynthesis and transpiration modifies sound: the rhythm, melody, texture, tempo and harmony shift with atmospheric conditions and tree response – electronically.”


The trio act like performative sound painters on Plein Air. The outcome has a droopy quality on Alder, that seems like a retro flashback, like the accompaniment to a silent movie. This continues with gaseous exhaust and flourishes of organ and mysterious tones right into Oak and through the manipulated forest. Having taken a decade to orchestrate this, there were obviously a lot of technical aspects to overcome in the process – but this blend of scientific photosynthesis, etc. has a great impact on the pleasant awkwardness of the chords. This has the presence of something circus-like, or perhaps an organ grinder in the streets of Paris circa the 1950’s – it’s impossible to peg, and exciting to contemplate. Having been recorded in Scotland there lays the essence of the place in the tonal shadows.


The contraptions they’ve built (have a closer look here) seem more akin to those used by old school land camera photographers, and those who engage in the camera obscura than your typical musician – but they have successfully fused sound and vision with natural science to deliver an awesome ear-opener as well. The computer generated sounds are within their own world of improv, and the artists here definitely had to rely on chance for all of their inventiveness, in part. As light and temperature effect the sounds that come alive, this is one of those projects that would rightly deserve a fine museum exhibition, if you could bring the outdoors in (I’m thinking of the Isabella Stewart Gardner Museum with its open air courtyard that already has plant life). But the idea of seeing a sight such as this trio upon a hillside or in a public park would be a head-turner for sure.


Side two is fully dedicated to the solitary Pear as it runs just about twenty-five minutes: ” (the) regional heritage pear tree leaf that sounds more like Minimal Music. During the Cologne Tree Sound Study, we made the recording in a small office room in 2015, we had less dramatic weather changes. A warm summer, smooth light changes, generating a more gentle soundscape to deeply plunge into music (Georg Dietzler).” This track stands out from the rest, and it’s great to be reserved as such. The effect is a tad psychedelic, almost like music within Eastern traditions (like a snake charmer), and a bit removed. Though this also has plenty in common with German electronic music of the 1970’s, in all its futuristic, minimalistic glory. Plants are earthly beings, here given voice in a most unique way.


Frans de Waard | VITAL WEEKLY
A subject about I surely have very little knowledge of is that of bioacoustics; you know, where biological events turn into sound. I know John Cage experimented with plants, Michael Prime also, and I’m sure there is much more out there, but I have not much idea about that. Silva Datum Musica is a duo of Tim Collins and Reiko Goto and together they created a ‚plant-driven synthesizer‘. It uses sensors and software „to generate real-time tree leaf data. Light, photosynthesis and transpiration modify sound: the rhythm, melody, texture, tempo and harmony shift with atmospheric conditions and tree response – electronically“, which is a pretty cool idea. Ideally, every plant sounds different, one would think. Here we have two different recordings, both live. One side has four pieces, recorded in 2017 in Scotland and one long piece from Cologne in 2015. The four pieces are ‚Alder‘, ‚Oak‘, ‚Elderberry‘ and ‚Birch‘ and ‚Pear‘ is on the other side. The interesting thing is, but perhaps also sad to note, is that those four pieces sound kinda similar. I have no idea if that is the trees, leaves or perhaps the software; basically, because I have very little knowledge of how this software is supposed to work. Are there elements of sound in there that are activated by the plants and as such maybe that’s why some of this sounds the same. It makes it, perhaps, more the result of a scientific experiment, rather than some music that works as a standalone thing, which is, I think, what this should boil down to. No matter how interesting it is to translate the sound of leaves into music, one should also consider the fact that it is now ‚out there‘, on an LP, to enjoy. One doesn’t see or smell the plants, nor the machine to translate them, and therefore it is a bit difficult to understand why these pieces sound relatively the same. The long piece on the other side, curiously enough, sounds a bit different, although one can link both sides together. The sheer minimalism of all of the pieces is, however, something I enjoyed very much about this. It is slowly evolving and that is always a great thing!
