Better known as the monotone emcee from N.Y. hip-hop kingpins Gang Starr, Guru also released albums with his side project Jazzmatazz. While their first two LPs recruited aging jazz masters, the third edition finds him teaming up with a variety of R&B singers, including Erykah Badu, Angie Stone, Kelis and Bilal. The Premier-produced "Hustlin' Daze" is a standout.
