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.Well, they're back in tonight's Brief But Spectacular, as part of our arts and culture coverage, Canvas.People ask me, what do I do? What's in this case? I tell them that it's a viola. It's a violin.And their response is, you don't play classical, do you?Is that what you do? No. With a serious face. Not you.Not classical, right?There's no way you ...Our whole life, everybody was like, even in my family, they were like, why you got -- you have Kevin playing the violin.It's not -- he's not supposed to be doing that.I always listen to those type of things, and I'm like, oh, well, I guess we're not supposed to be violinists because we're Black?Well, we're going to be the Blackest violinists you have ever seen.We approach it very, very classically. But -- so the violin part of it is always very baroque, Bach, Mozart-like, not much sliding, not much jazz.But the beats and everything that's around it is hard-hitting, dirty.
