Some of the pieces, such as "Keys No Address", or "B.C." are clearly composed, others, like "Iris" and the long "Splits" are free improvisations that could evolve in any direction. And that's the great part of this album : you hear it all: the history of jazz in a nutshell (Gillespie/Roach, Don Cherry/Ed Blackwell to Dixon and beyond), technically broad, creative and inventive, and with loads of passion.
Listen to some tracks of a perfomance at WFMU which will give you a better idea of the music on this album.
