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.

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.

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!

The Leap of Faith Orchestra is a large improvisation ensemble comprised of 5 ub-units--Leap of Faith, Metal Chaos Ensemble, String Theory, Turbulence, and the New Language Collaborative--all assembled here for a massive and far-ranging experience, scored with time indices and English language descriptions by leader David Peck; dense and spectacular.
