Crockspot where ya been??

Your friend has a beautiful voice, glad to hear it. Sierra Hull's debut album, Secrets, is a solid collection of bluegrass. As good as she is on the guitar, the mandolin is her prime instrument and she can really get going. You're spot on that bluegrass is meant to be played. I've got an itch to try my hand at the banjo if I can find a good used one.
Side note, why is it that bluegrass festivals are attracting more and more dirty hippies? Is it just my neck of the woods? As an early Christmas present I got a documentary that covers a 1972 (IIRC) multiple day bluegrass festival, complete with a teenaged Ricky Skaggs coming into his own on the mandolin. Nearly all the people in attendance are decent, civilized, polite, respectable folks. Nowadays, if I'm at a festival, it seems I can't take 3 steps without tripping over some drooling half-a-moron laying in his or her own vomit. What gives?
