Nuttin’ But Stringz is “an intense blending of classical music, jazz, r&b, and yes, hip hop.” Playing violins to heavy beats? Yes, sir. They have one song on iTunes and the other song on their website costs $6.99 (oy!). Alternatively, you can just watch a flash video of them on The Tonight Show with Jay Leno.
Update (May 4, 2009): You can actually now listen to “Broken Sorrow” at their official website (copy and paste the URL): http://www.nuttinbutstringz.com/01.mp3
