Query: Free Improv with Perfect Chemistry

"Spoken Once" is not your father's jazz. Saxophonist T. Taylor and pianist Chris Forbes have recorded a cutting-edge jazz album of free improvisation coupled with sheer musical chemistry. Those with an ear and a taste for the complexities of assonance will find themselves engaged by the many levels the duo bring to their improvisation. Musical laments build to exuberance, and exuberance gives way to the hushed simplicity of a few isolated notes. The spectacular part of this CD is that the more you listen to it, the more you get out of it. I'm on my fourth listening, and I am still astonished by some of the musical turns. My favorite cut, "Petrin Hill," is over twenty minutes of music that won't let go.I highly recommend this CD for jazz aficionados, particularly for those who appreciate the immediacy and power of improvisation.
