This calypso concert, sponsored by People's Songs and hosted by Alan Lomax, was performed in December 1946 at New York's Town Hall during the post-World War II calypso boom in the United States. Three of the greatest New York-based calypsonians, Lord Invader, the Duke of Iron and Macbeth the Great, are accompanied by Gerald Clark & his Invaders, performing a mix of well-known and, especially in Invader's case, original material. These CDs are a sentimental journey back to an historic performance of early calypso in the U.S. and back to the era when progressive politics and folk music were joined. Part of a series of concerts (Blues at Midnight, Ballads at Midnight, etc.) staged between 11 p.m. and 1 a.m., which offered a lively after-theatre destination for New Yorkers, this was no ordinary set. Here is a sweeping overview of the many forms of Trinidadian folk music performed live in concert.
