Gang Starr - Jazz Thing. Best example of Jazz and Hip hop fusion. Way before US3 btw.

Guru feat. MC Solaar - Le Bien Le Mal

From Guru’s Jazzmatazz Vol.1 (1993). 

A unique blend of Guru’s smooth flow and MC Solaar’s elaborated rhymes. A mix of poetry, jazz with a unique flow rapped in English and French.

Unbeatable.
