The Bluegrass Cardinals are one of the earliest bluegrass groups I was exposed to, and this song, "Jubilee Road", reminds me of being a toddler and my dad cranking this album on the stereo and playing along. It has a great Cajun fiddle rhythm that instantly recognizable. A few years ago I picked up this CMH Records collection and it is, as the name claims, the definitive collection. Buy it here.
