Quincy Jones, Back on the Block, 1989 on Qwest.

My copy is from the Vinyl Me, Please anthology Story of Quincy Jones.

Late 80s QJ with a ton of guests from hip hop, jazz, soul: Take 6, Big Daddy Kane, Ice-T, Kool Moe Dee, Chaka Khan, Ray Charles, and many others

Eclectic but very rooted in a late 80s sound
