I can't find any samples but below is the writeup from Dusty Groove:
A really hard-hitting groover from the great 60s trio of Les McCann – a set that adds in some extra guitar from Joe Pass, who definitely sounds his most soulful on the set! Joe grooves perfectly with Les' piano – and has almost a Kenny Burrell-like depth in tone throughout – one that we're not as likely to hear on other Pass sessions of this vintage, possibly because of the excellent rhythms from Paul Chambers on bass and Paul Humphrey on drums! Tunes are definitely the soul hits promised in the title – mostly numbers that were brimming up big in the soul jazz generation of the time, but given a particular Les McCann twist. Titles include "Sister Sadie", "Bag's Groove", "Back At The Chicken Shack", "Work Song", "Sonnymoon For Two", "Groove Yard", and "Sack O Woe".
