Metal Chaos Ensemble, formed in 2015 as a working project to explore rhythms on metallic instruments guided by rules-based chaotic systems of a very large number of small components, in a quintet studio recording using three dedicated drummers, reeds, electronics, and accompanying "tape" mixes, resulting in epic, inspired and wonderfully unpredictable improvisation.

A 2019 performance in Cambridge, MA of this intertwining quintet of unique instrumentation, with PEK on bamboo & bass saxophones, clarinets, contrabassoon, tarota, melodica, sheng, aquasonic, wood, metal, wind siren, crank siren, & chimes; Glynis Lomon on cello, aquasonic, & chimes; Eric Zinman on piano; Syd Smart on percussion; and Yuri Zbitnov on drums, gong, wood, metal, wind siren, & chimes.

The largest ensemble of Boston-area David M. Peck's Leap of Faith collective using Peck's frame notation compositional method of written descriptions and graphic symbols to allow large ensembles to create major works without extensive rehearsing, accompanied by a 23 page booklet that illustrates that concept and details this 2018 Killian Hall, MIT, concert.

Wind player David Peck and percussionist Yuri Zbitnoff formed Metal Chaos Ensemble to explore chaotic rhythms on metallic instruments, employing an arsenal of percussion, electronic and wind instruments, becoming one of Evil Clown's most prolific sub-units, here with Bob Moores on space trumpet & guitar, Eric Woods on analog synth, and Eric Zinman on percussion.

The core of Leap of Faith Orchestra--David Peck on reeds and winds, Glynis Lomon on cello, aquasonic & voice and Yuri Zbitnoff on drums & percussion-- joined by Eric Zinman on piano, recorded at Outpost 186 in Cambridge, MA, where Evil Clown has a residency on the third Saturday of each month, presenting a variation of subunits from one of their larger units.

The 4th work using composer, band-leader and multi-instrumentalist David Peck's Frame Notation Scores for his large ensemble Leap of Faith Orchestra, his graphic notation allowing exceptional, unexpected and truly unusual results in large-scale improvisation, an amazing evolution of the big band concept executed by the some of the finest players in the Boston area; amazing!

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.
