Videos not the greatest

I remember countless Thursday nights sitting at that club, watching that band.
The late 70's to mid 80's were a magic time in DC for bluegrass.

Witnessed Everybody from Paul Kraft, Lowell George, Emmylou, Linda Rondstadt, Grisman, Tony Rice,Buddy Emmons, Earl Scruggs,Ricky Skaggs, Buck White, (and on and on) show up to sit in.

It may not be my style of music, nevertheless, the talent shines through. Quality performances, and it's great that this has been recorded and retained. Exceptional.
