well, the Andrew Hill isn't the only Warwick record that TCB booted. They also did the Donald Byrd/Pepper Adams and the Teddy Charles. Those TCBs sound gawd-awful!
I like the Ping 45s but agree that South Side hard bop and soul jazz is a long way from what Hill was doing on Blue Note ten years later. That said, Hill could also pen some in-the-club groovers, as he did for Morgan and Mobley.
