Chris Thile (pronounced Theely). Mandolin virtuoso.
Started playing when he was 5. Formed Nickel Creek (not Nickelback) with Sean and Sara Watkins when he was 8. Signed a record deal when he was 12. One of his projects, Punch Brothers, is a real genre bender. He is now the host of A Prarie Home Companion.

Here’s one when he was much younger playing at Floydfest.
And for the more sophisticated out there, how about some Bach.
