Designed for all rhythm section players and teachers. Listen to the CD as you would any jazz recording as the melody is played in and out and the musicians solo, comp., and trade "4s." Then, using your stereo balance control, eliminate your part and sit in! Tremendous tool for teachers; allows isolation and careful study of each instrument's role with definitive chapters in the booklet written by the artists. Includes piano & guitar voicings, transcribed bass lines, outstanding drum information, and transcribed solos by Haerle, Petersen, and Coolman. This is the first play-along where the drummer can be turned off and students can trade 4s and 8s with the pros (Volume 30B only). Rhythm Section: Dan Haerle (p); Todd Coolman (b); Jack Petersen (g); Ed Soph (d).
