Cloud controlled oscillators

Interesting siren-like drones from this experimental instrument –

6 oscillators being triggered by light sensors reacting to the movement of the clouds across the sun – followed by a composed 16 min soundscape where each of the 6 oscillators are fed through echo’s and reverbs.

They seem to sound a little sad every time the clouds roll in . . . understandably so. – Link
