Every November musicians from all over Latin America come to take part in the international music festival at Varadero in Cuba. For five days bands from all the 'other' Americas vie with each other in a virtuoso display of music - music which is, astonishingly, almost unknown in Britain. Last month Arena went to Varadero to capture the event, and tonight presents the finest in contemporary Cuban and Latin American music. With Irakere and Arturo Sandoval; Los Van Van, Cuba's most popular dance band; soul calypso by Dimension Costena from Nicaragua; and bands from Venezuela, Puerto Rico, Mexico and Uruguay.
