Lowell “Sly” Fillmore Dunbar (born 10 May 1952, Kingston, Jamaica) is a drummer, best known as one half of the prolific Jamaican rhythm sectionand reggae production duo Sly and Robbie.

Dunbar began playing at 15 in a band called The Yardbrooms. His first appearance on a recording was on the Dave and Ansell Collins album Double Barrel. Dunbar joined a band Ansell Collins called Skin, Flesh and Bones.

Speaking on his influences, Sly explains “My mentor was the drummer for The Skatalites, Lloyd Knibb. And I used to listen a lot to the drummer for Booker T. & the M.G.’s, Al Jackson Jr., and a lot of Philadelphia. And there are other drummers in Jamaica, like Santa and Carly from The Wailers Band, Winston Bennett, Paul Douglas, Mikey Boo. I respect all these drummers and have learnt a lot from them. From them, I listened and created my own style. They played some things I copied, other things I recreated.”

In 1972, Dunbar met and became friends with Robbie Shakespeare, who was then bass guitarist for the Hippy Boys. Shakespeare recommended Dunbar to Bunny Lee as a possible session drummer for the Aggrovators. Dunbar and Shakespeare decided to continue performing together. They worked with Peter Tosh and his band until 1981, recording five albums.

Dunbar noted about the Mighty Diamonds‘ song “Right Time”: “When that tune first come out, because of that double tap on the rim nobody believe it was me on the drums, they thought it was some sort of sound effect we was using. Then when it go to number 1 and stay there, everybody started trying for that style and it soon become established.” According to The Independent, the entire album Right Time was “revolutionary”, the breakthrough album of “masters of groove and propulsion” Dunbar and Shakespeare, with “Sly’s radical drumming matching the singers’ insurrectionary lyrics blow-for-blow.”

Dunbar and Shakespeare formed their Taxi Records label in 1980. It has seen releases from many international successful artists, including Black Uhuru, Chaka Demus and Pliers, Ini Kamoze, Beenie Man and Red Dragon
