Before it was synonymous with a painful depilatory procedure, the word "Brazilian" evoked sumptuous, hypnotic music combining Tin Pan Alley melodies and African rhythm in ways that make rock seem like crude kiddie music. Like some of his better-known musical countrymen, Brazilian percussionist CYRO BAPTISTA mines New York for inspiration. Instead of Tin Pan Alley, however, Baptista fuses his rhythmic inventiveness with jazz and avant-garde. He plays Thurs., AUG. 30, with his theatrical and comical ensemble Beat The Donkey.
