I certainly can't tell from this that Frank Foster made his bones playing (and composing) for Basie and later led the Basie Orchestra after Basie's death. More like a Jazz Messengers' date with elements of late '60s Miles Davis. Here, Foster reminds me more of Coltrane, Wayne Shorter and even Sam Rivers than Lester Young.
I liked Stephen Scott playing with Sonny Rollins and he does a nice job for Foster as well. Tasty Christian McBride arco interlude on When April Comes.
