Jazz Beat: Deborah Brown, at the Blue Room

Kansas City jazz singer Deborah Brown happens to be an international star, better known in Europe — where she spent 12 years — than in her hometown. She has appeared with orchestras in Russia, Denmark and Sweden, and she has performed with an enviable list of jazz greats, including Clark Terry and Johnny Griffin. To hear Deborah Brown — when her voice is vividly rising over a bebop line, massaging a ballad or scatting to swing — is to hear a recognized master of jazz. And yet, she’s barely known in Kansas City, where she lives. On Saturday night, the Blue Room offers Kansas Citians a rare chance to discover a talent that the world relishes.
