Here's a wonderful recording by Alan Lomax of a concert performed on 21 December 1946. The performers include Lord Invader, Macbeth, and The Duke of Iron - all outstanding Calypsonians. Preceding every song is an introduction or dialogue by Lomax and each artist - greatly informative and highly entertaining. If you were at all interested in the previous post's citation from Lyotard, you'll love this. Lomax and the Calypsonians spend a lot of time discussing the importance of folk traditions and how they serve to share knowledge among Caribbean people. Definitely check out "Do Lai Do", a traditional Trinidadian work song. Sadly, I cannot find the original liner notes, but if I find them I will post them.
Get it here: Calypso at Midnight!
