This giant 16-CD Galaxy set features Pepper at the peak of his powers. Most of the performances are in a quartet setting, although this collection also includes a session with strings, five unaccompanied alto solos (he also plays clarinet on a few tracks), and a pair of CDs in which Pepper performs duets with pianist George Cables. Although more general collectors may want to acquire some of the individual sessions first (most of which are available separately on CD), the more dedicated jazz fans are advised to save their money and acquire this essential package.
