In search of some live Brazilian music a few months ago, I found my way to Dizzy’s Club Coca-Cola, in the Time Warner Center, where the Brazilian percussionist Duduka Da Fonseca was leading a quintet. I can’t say I knew much about Mr. Da Fonseca before I heard his band that night, and among the things I didn’t know was that his quintet’s regular reed player was a 38-year-old Israeli woman named Anat Cohen, who has lived in New York since 1999.
