transcribed by Greg Lui. Finally! Piano Comping transcribed from our best-selling Volume 42 - Blues in All Keys! See how soulful jazz master James Williams negotiates the blues in all twelve keys, and you'll be ready for anything! Of course, the blues and ii-V7 voicings presented here are applicable to all other standards, as well. Those of you who already have the Vol. 42 "Blues in All Keys" CD will enjoy playing along with the bass and drums by turning off the right channel.
