Exploring chaotic rhythms on metallic instruments, this is an extended septet version of the Boston free improvising ensemble in a complex improvisatory journey of reeds, synths and percussion, performed by PEK on reeds, Mike Caglianone on saxophones, Boob Moores on trumpet & keyboards, Mike Gruen on bass, Steve Niemitz on drums and real time signal processing from Joel Simches.

With new drummer/percussionist Steve Niemitz, the Leap of Faith trio of PEK on clarinet, contrabass clarinet, alto saxophone, tenor saxophone, musette, tarota, bass tromboon & sheng, Glynis Lomon on cello, aquasonic & voice, and Niemitz on percussion recorded this session at Bonnie Kane's monthly Thursday Night Experiment in Western Massachusetts.

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.

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.
