When Kev Marcus and Wil B met in a high school music class they shared their desire to disrupt people's impressions of what classical music should be. Together they formed a group called Black Violin, which we featured on the NewsHour early on in their success. Now they're back with a Brief But Spectacular take on defying stereotypes, as part of our coverage of arts and culture, "CANVAS."
