The first side consists of a Duo for Violin and Cello by Giacinto Scelsi, a drone piece with just a tiny leavening of melody, excellently played by Aisha Orazbayeva and Lucy Railton. It's got a mystical power to it and it's quite subtly uplifting, excellent stuff. On the flip side are two Scelsi-inspired works. Chris Watson's Invertebrate Harmonics is, for the first two minutes, essentially a drone piece made from field recordings of insects; for the rest, a mysterious resonant sound that certainly sounds synthesized joins the swell. And Joe Browning performs Buddhist monk standard Honshirabe on a shakuhachi (which, as you know, is a Japanese end-blown flute). Both are fascinating in their own right and excellent companions to the Scelsi.
I bought this from Boomkat. They call it Modern Classical / Ambient.
