Composer Henry Threadgill's Double Up band does not include Threadgill himself, but for this second release with the group he adds a 3rd piano (also doubling on harmonium) alongside two alto saxophones, cello, tuba, drums and percussion, the octet performing Threadgill's complex yet effortlessly intricate and distinctive compositions that allow his performers to shine.

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.

Henry Threadgill's tribute to friend, composer-conductor Lawrence D. Butch Morris, in a detailed 4-part work with an excellent set of improvisers: Henry Threadgill, Jose Davila, Jason Moran, Christopher Hoffman, David Virelles, Roman Filiu, Curtis Macdonald, and Craig Weinrib.
