Mel Lewis' playing here is incredible. To put it bluntly, this is a perfect example of someone swinging his a$$ off!
I saw Mulligan's 1980 Concert Band in concert. A little different than the 1960 version, no big "'star" musicians like Zoot or Clark Terry or Brookmeyer, but still swinging with Gerry's wonderful comp/arrangements and his great baritone playing, still understated as far as typical big bands go, but still really good, perhaps for that very reason.
