Boston area composer and multi-instrumentalist David Peck developed a unique approach to scoring for this large and idiosyncratic ensemble, referred to as Frame Notation, giving descriptions of sonority, time scale, events, playing occurrences, &c, leaving a great deal of freedom for these extraordinary musicians, as borne out in their incredible and extended performance.

Started in 1995 as an interdisciplinary unit of improvisational artists led by Boston area reedist/multi-instrumentalist David Peck and cellist Glynis Lomon, exploring multi-phonics, glissando, microtones, graphic & descriptive scores, and extended techniques, expanding the ensemble with like-minded musicians, here in this 2017 recording of full 24-piece orchestra.

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.
