I was fortunate to get to see JD Crowe and Tony Rice play together a couple or more times.

You really can't beat the line up JD had on his album "JD Crowe and the New South", Rounder 0044. It's the holy grail of bluegrass albums.

JD Crowe - banjo/vocals
Tony Rice - guitar/lead vocals
Ricky Skaggs - fiddle/mandolin/vocals
Jerry Douglas - dobro
Bobby Slone - bass/vocals

Here is a good article about the short lived band and the impact of that album;
