Plein Air the album presents recordings from a plant-driven synthesizer. A custom built 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 sounds of each leaf of regional deciduous trees by scientifically sensored data-sonification are much more musical than one could imagine. Their timbre and volume always depend on light and temperature, number of audience. It varies from site to site and from country to country. We can hear loops of rhythmic sequences, groups of tiny computer generated signals, long drones which change constantly and are hard to describe.
