File somewhere between electronic, jazz, classical and folk, with a little mbira on top. Sometime I'll get around to posting Schwab's album "Meditation", which is up there with some of Ashra's longform guitar workouts of the 70's. And Jasper Van't Hof's explorations of African music and collaborations with Archie Shepp, Markus Stockhausen, etc. will get their due soon too. Guitar, flute, woodwinds, thumb piano, acoustic piano, synths... give your ears a highbrow sound bath.
