Whether with the groundbreaking group Rufus or on her own, Chaka Khan has one of the most distinctive and influential voices in R&B. She's able to wail at full emotive throttle or deliver a love song with nuanced jazz-inflected tones, and sometimes even do both within the same track. This 1996 collection gathers some of Khan's biggest and most beloved solo efforts. Included here are the classic tangy attack of "Ain't Nobody" and the turntable-enhanced smash "I Feel for You"
