I love bluegrass music. Seriously, a third of the of my mp3 player is Sara Watkins, Mountain Heart, Cherryholmes, The Del McCoury Band, The Lonesome River Band, IIIrd Time Out, Nickel Creek, Dan Tyminski, and, of course, Alison Krauss. I even have some bluegrass versions of other artists' catalogs (i.e. "Pickin' on John Mayer" or "Pickin' on Coldplay").
The other 2/3rds of my mp3 player is pretty eclectic: Taylor Swift, Johnny Cash, Avett Brothers, Frank Sinatra, Cat Stevens, Brooke Fraser, Cross Canadian Ragweed, Metallica, Eminem, Janis Joplin, Page CXVI, Simon and Garfunkel, Better Than Ezra, Norah Jones and about 10,000 other songs.
For those of you who aren't bluegrass fans, I thought perhaps you would enjoy some bluegrass covers of popular songs. Here are two I highly enjoyed:
The Cleverlys covering the Black Eyed Peas "I Got A Feelin'"
Nickel Creek covering Britney Spears' "Toxic"
(I saw Nickel Creek do this cover live in Chapel Hill back in 2005.It was my second favorite part of the show. My favorite was their cover of "Short People".)
