Sex Mob is a band of the now: post-modern waltzes mutating into dub-echoed free jazz. Sex Mob is social music: a rollicking midnight set with clatter and drinks and a band. Sex Mob is a happy contradiction: an experimental jazz outfit whose music has slid readily into the mainstream via Saturday Night Live, MTV, and National Public Radio. They will play Duke Ellington, Nino Rota and James Bond.
