Pink Martini's blend of American swing, Latin rhythms and chamber arrangements, along with vocals in five languages, give the group's largely original material mass appeal - meaning the audiences consist of people who normally don't sit next to each other. Thomas Lauderdale of Portland, Oregon, founded the "little orchestra" Pink Martini in 1994. It has gone on to become a genre unto itself. We adore the band's cosmopolitan mix of Disneyfied Latin rhythms, cabaret Orientalia and Arabic tunes kissed with carnival atmospherics and ragtime horns.
