(Erasure's The Two Ring Circus features his earliest dabblings in the studio.) His first nightclub residency was at the Devil's Nest, in the Bronx, and later he moved to Roseland, Studio 54 and the Palladium in Manhattan. During the 1990s, Vega was playing at one of the most influential nightclubs for house music, The Sound Factory Bar.
