Mark performs with and manages Emergency Exit Art's bands, the Bollywood Brass Band and Crocodile Style. He is a founder member of both groups (in 1987 and 1992 respectively), playing baritone sax. As the Bollywood Brass Band developed its stage presentation, he moved offstage to become the band's VJ, projecting video sequences from Bollywood films in sync with the band's live music. Mark has been involved with Emergency Exit Arts since 1987, and was General Manager of the company in the late 1990s.
Mark has been animating the street with music since starting his career playing on anti-nuclear demos in the early 1980s. His involvement with the International Festival of Street Music led to the birth of the Bollywood Brass Band through a collaboration with India's Shyam Brass Band.
Mark was a longtime member of radical big band The Happy End, recently played with poet and singer John Hegley, and once recorded in the Beatles favourite Abbey Rd #2 studio with an all-star band including John Entwistle from The Who, Georgie Fame and Ringo Starr's son.
He writes for world music magazine Songlines and has taught Music Business at Kingston University.
