Hear David Liebman solo over every scale listed in the Scale Syllabus. David solos on two versions of each scale. First is slow/simple and the second is more complex and fast. Stereo separation allows you to practice and improvise, too! Piano and guitar, too. David is on one channel and Jamey is on the other. Piano and guitar players can accompany or solo. Not only can you hear the different scales, you can practice or solo with them by turning off the sax or piano channel. There is an excellent list of suggested piano voicings in the supplement. This is a great way to learn new scales and chords. Enjoy as you would any jazz recording and let your ears get accustomed to exciting new scales.
