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.

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.

One of the Boston area's incredible, eclectic collective organizations from David PEK's Evil Clown is Turbulence Doom Choir, a quintet with three brass players, drums, reeds, and a variety of percussive, wind instruments, game calls, &c., presenting large scale improvisations of uniquely evolving approaches, instrumentation, and heavy rhythms, a powerful brew.
