I stumbled upon this video of a research community's efforts to amplify music and expression produced by plants. Baloney? Maybe so, but nice to think about. Reminded me of ambient soundscapes.

Yep, that sounds ambient, I think you can sell your idea to Fever Ray or sth By the way, have you heard the music produced by stars? Not really the stars but Pulsars. Check it out, they sound really mystical!
