Boris Peter Bransby Williams (born 24 April 1957)[1] is an English musician, best known as the drummer for The Cure from 1984 until 1994, and for forming the band Babacar in the late 1990s.

He first played drums in local bands with future Cure bandmate Roger O'Donnell and originally focused on jazz fusion.

[3] He was also known for his innovative drumming style, with Freaky Trigger saying: "[He] is a god among drummers due to his complete willingness to create an entire beat based on doing rolls on the various toms in his kit.

"[4] Williams has been cited by Billboard for his subtle but forceful drumming, "improbably stealing the show from his bandmates";[5] and critics often praise his technical and timekeeping skills.

[9] Williams contributed to new acoustic versions of Cure songs that were recorded for their Greatest Hits compilation in 2001, though he did not officially rejoin the band.
