Ninja Tune gets happier as 100 releases approach, and the 96th is a nice one for both their mood and ours. The Floating Glass Key in the Sky is the debut offering of Rainstick Orchestra, two DJs who met four years ago in Japan. RO takes up guitar, piano, bass, and sequencers, emulating the minimalist experiments of John Cage and Steve Reich within jazz thresholds with a touch of Detroit techno and atmospheric hip-hop. If you like Cinematic Orchestra, Bonobo, Mouse on Mars, and Mr. Scruff, give Rainstick a shake.
