I agree with many of the obove answers........ go back to Bill Monroe, the Stanley Brothers, Flatt and Scruggs etc. then check out some of the more modern stuff too Hot Rize, (Tim O'Brien solo as well), New Grass Revival, Tony Rice etc. Be well rounded, blue grass is great music especially if you dig a little (check out some of the old Vanguard or Smithsonian issues of Kentucky mountain music (Clarence Ashley etc.)).
