Despite its title, this was actually the third album by Buddy Rich's still-new big band. The recording is taken from two different periods that, although only five months apart, find the band undergoing some major turnover; only six of the 15 sidemen are the same. With such players as altoist Ernie Watts, trumpeter Chuck Findley, and usually Jay Corre on tenor, this was a strong outfit. Most of the material (other than "Chicago" and "I Can't Get Started") was new; among the high points are "The Rotten Kid," "New Blues," and the complex "Diabolus."
