Lester Young: Lester Young / Buddy Rich Trio (Verve)

The Lester Young Buddy Rich Trio is a jazz trio album recorded in Hollywood, California in March–April 1946 by Lester Young, Nat King Cole and Buddy Rich.

The first 4 tracks were originally released on Mercury Records as The Lester Young Trio. The remaining 4 tracks were released on Norman Granz' Clef Records label as The Lester Young Trio No. 2 before all 8 tracks were combined and released by Granz' Norgran Records label as The Lester Young Buddy Rich Trio. Nat King Cole was under contract with a different record label at the time so was credited only as "Aye Guy" on the original Mercury / Clef / Norgran releases.
