Niehaus Basic Jazz Conception Vol 1

The Play-Along CD included with this book was recorded by professional
musicians playing in three keys. Tracks 1-11 are in Eb, tracks 12-22
are in Bb, and tracks 22-33 are in C. In addition, the exercises in
the beginning of the book are played on tracks 34-45.
Each track is stereo, simply pan between your speakers to eliminate of
include the saxophone in the recording. This enables you, the student,
to either hear the music, or play along with the piano, bass and drums
by eliminating the saxophone from the recording.
