Ambiance Lunch Hour Theatre Club was founded in 1968 by American playwright and producer Ed Berman MBE. Located in the basement of the Ambiance restaurant, Queensway, London, the lunchtime theatre played an important role in creating infrastructures to support writing by black, women, and gay writers. In the summer of 1970 Berman produced the 'Black and White Power' season at the Institute of Contemporary Arts, which launched the career of Trinidadian playwright Mustapha Matura. Two of the actors involved in the season, Alfred Fagon and T-Bone Wilson later became writers themselves.
