Heard these guys on the Tonight Show. From their website:
When you first spy the New York duo's
streetwise style, you may expect them to start rapping, but then you
hear their violins, and an entirely profound and altogether surprising
sound awakens from their souls. Dubbed N.B.S or Nuttin But Stringz, the
talented young musicians play an intense blending of classical music,
jazz, r&b, and yes, hip hop.
They've got a 30-second audio clip available.
