Dennis Chambers (born May 9, 1959) is an American drummer who has recorded and performed with John Scofield, George Duke, Brecker Brothers, Santana, Parliament/Funkadelic, John McLaughlin, Niacin, Mike Stern, CAB, Greg Howe, and many others. Despite a lack of formal training, Chambers has become well known among drummers for his technique and speed. Chambers is particularly regarded for his ability to play "in the pocket" but can also stretch very far out of the pocket which is also a hallmark of his technique. Chambers exhibits a powerful style that is technically proficient, yet highly musical and groove-oriented. He can play in a wide variety of musical genres, but is perhaps most notable for his jazz-fusion, funk, and Latin music playing. He is mostly known for his fast hands and triplets on the bass drum. He has helped many young drummers, the most prominent being Tony Royster, Jr.
