Tony “Asher” Brissett is a Jamaican reggae keyboardist, synthesizer player and riddim producer, also known as King Asha. He became active in Jamaican music during the roots reggae era and continued working through the transition to digital dancehall.

Brissett is associated with the development of the Sleng Teng rhythm, which helped transform Jamaican dancehall in the mid-1980s. The rhythm originated from a Casio keyboard pattern brought to producer King Jammy by Wayne Smith and Noel Davey. Jammy slowed the pattern down and added percussion, while Brissett contributed piano and percussion to the recording. Released as Wayne Smith’s “Under Mi Sleng Teng” in 1985, the track became a landmark in the rise of digital reggae.

As a session musician, Brissett has performed on recordings spanning roots reggae, dancehall and later digital productions. His credits include Culture’s *One Stone* (circa 1980), and he has continued to contribute keyboard and synthesizer parts to recordings by Jamaican and international reggae artists. He is also associated with the King Asha name and the T Ash Muzik label.
