Classical music may not be as elitist as some claim, but there’s no disputing the obvious fact that it attracts almost none of America’s famous racial diversity. In fact, an African-American musician in a symphony orchestra is such an unusual sight as to be jarring, and token attempts to bridge the racial gap have generally been short-lived and unsuccessful. So when an entire ensemble of minority musicians starts to achieve commercial and critical success with a classical product, it’s worth taking note, and Imani Winds, which brings together African-American and Latino composers and performers with an interest in serious new music, is establishing itself as a unique voice in the lily-white classical wilderness.
