New York composer and drummer Carlo Costa assembled this accomplished ensemble of NY improvisers for a live performance at IBeam in Brooklyn, capturing his piece "Strata" that evolves layers of sound from very sparse to densely yet accesibly stacked sound, varying recurring material to change perspectives in the aural space as the piece progresses; impressive.

Composer, saxophonist and flutist Henry Threadgill presents 2 full-length works for his 15 piece band "14 or 15 Kestra: Agg", as he explores new ways of integrating composition with group improvisation, here using an entirely new system of improvisation based on preconceived series of intervals realized in multi-layered counterpoint, rigorous polyphony, and timbral contrasts.
