The other day I was on Amazon MP3 and saw a free download (still free as of this writing) from Steve Martin. At the time, I thought the name was just coincidence, but then I saw this article in the Times about how Steve Martin plays bluegrass.
There is free music from Smithsonian Folkways (downloadable as an MP3, no signup or registration required) at this link:

Right-click on the MP3 link to download them.
Check out Rabbit in a Log by The Stanley Brothers. It has some wicked good banjo picking.
One of The Stanley Brothers is Ralph Stanley, who did the "O Death" song in O' Brother Where Art Thou (this is the scene during the KKK rally)
