mostly stuff my uncles taught me. i like norman blake A LOT. doc watson and tony rice are pretty great to listen to (i don't know if purists consider them bluegrass or just hot picking music), but hard to keep up with. flatt and scruggs. the dillards. any contemporary stuff you might suggest?
old and in the way ain't that bad either...
I love Doc Watson, even though he might more properly e classified as Piedmont Folk and Blues, he is the man whatever label is put on his music. Tony Rice is perhaps the best acoustic lead player I've ever heard, he has a level of "gettin' it" that no one else seems to have period, end of story. While the Tony Rice Unit isn't exactly traditional bluegrass he did those Bluegrass Album Band records with J.D. Crowe, Doyle Lawson and a few others that is as hard drivin' as it gets. If you haven't heard J.D. Crowe and the New South they are top notch. The first album is up there with the best acoustic records made. The band, featured JD Crowe, Tony Rice, Ricky Skaggs, Jerry Douglas, and Bobby Sloan (violinist with the king - Bill Monroe). I ran sound for him once, he's a real nice guy and his current band is great. If you like Doc Watson, check out Wayne Henderson. He's a mailman from Rugby, VA (about an hour from me in Blacksburg) and one of the best acoustic guitar builders on the planet. He's one of the few guitar builders out there who can play and build at the same, very high level. He's a great guy too, I go to his Christmas party every year - it's a blast. Met Doc Watson there, and got to play with the Kruger Brothers (a Swiss Bluegrass band that is also worth checking out). A lot of this contemporary bluegrass is kind of watered down IMHO - some great players but the music is sterile. Bluegrass should be earthy and hard driving of you ask me - not pretty and well produced. If you want, I have a ton of stuff recorded send me a PM and I can get you some stuff. My favorite players are mostly unsigned "parking lot" pickers. Old and in the Way is what got me into bluegrass - though living in the beautiful Blue Ridge Mts doesn't hurt.
I've been playing in a bluegrass band for about 15 years or so and love it, here's a video of my band Crossties (our banjo player Timmy Mills is a pure and good as they come). Not the best recording, my drive crashed after getting 2 songs off it so that is all that survived. You can see what a traditionalist I am with my gypsy jazz guitar and Ramones shirt http://www.youtube.com/watch?v=0wOlTQjMakM
