(Instructional book with play-a-long CD) Think play-a-long and free jazz don't mix? Think again! Kenny Werner, recording artist and author of the best-selling book "Effortless Mastery," has put together with his trio this CD that breaks down all the traditional boundaries of rhythm, melody and harmony. He presents a blank canvas of sounds, pulses and colors to excite the imagination, and includes a perspective text that details ways to use this play-a-long CD to open new avenues of musical discovery.
