A double album of electroacoustic improv sessions from Sommerville, MA, centered around electronic artist Andrew Neumann on the Buchla Music Easel--a complex additive analogue synth--heard in quartet and trio sessions with Forbes Graham (trumpet), Sandy Ewen (guitar & objects), Junko Fujiwara (cello), Damon Smith (double bass) and Eric Rosenthal (drums & percussion).

A 15-member ensemble of Boston area improvisers plus guests Jeb Bishop, Tony Malaby and Taylor Ho Bynum, taking their name from the deep-sea submersibles used for exploring, as this band survey's large form improvisation that blends free and melodic jazz in adventurous ways.
