Oh my God! I listened this excellent album last time in the 1970s in mono from my audio cassette. I was a teenager boy and big fan of the jazz funk and jazz fusion genres. I still forgot it until now... Good to listen again!
Hard to beat the whole album for tightness. I bought it in '75 and have played it constantly ever since. Never get bored. Someone posted that it didn't swing - there's a definition misunderstanding going on there somewhere - Actual Proof is like a small band Basie piece and the break in Spank a Lee at 5.02 is worthy of any bebop combo.
