As part of series of programmes celebrating the Brazilian carnival and its music, Lucy Duran travels to two places famous for their Carnivals - Recife in the Northeast and Rio de Janeiro in the Southeast. She discovers some of the rhythms unique to Recife including maracatu, frevo and ciranda, recorded on a beach, in a cow-shed and in the old colonial city of Olinda. She also finds out about the mangue bit movement and its frontman, the late Chico Science.
