Being one of bluegrass's greatest fans, I think I can help. If you're just getting into bluegrass, you should start out with the standards like Lester Flatt & Earl Scruggs (google "Flatt & Scruggs"), Ralph Stanley, The bluegrass stranger( This band is up and coming), Allison Kraus and Union Station, Ricky Scaggs, Bill Monroe, The Osborne Brithers, the list goes on and on. Your choices really are not limited, there's a whole world of bluegrass music out there, sometimes you just need to know where to look, and what to look for. Feel free to PM me for some good suggestions, those are some of the best artists out there, but there are a million small, local bands that are truely awesome, you just never hear about them.
