While further exploring electro-acoustic territory, the two artists i AM esper and Mystified decided to collaborate. i AM esper is known for playing humming baritone guitar drones, and Mystified, more recently, for creating ambient drone textures from trombone notes. i AM esper laid down 5 nice tracks and Mystified remixed them, re-composing and processing the sounds. The result, Treetrunk feels, is quite powerful, covering emotions from total bliss to deep despair. Somehow the use of "real" instruments has brought these feelings out. Or perhaps it was the musicians themselves. Some references might be made to My Bloody Valentine on a track or two, for those who know of their music.
