Pearly Blue (sometimes called Down the Road) is an old Flatt & Scruggs tune which I learned while playing with The Bootleg Remedy back in NYC. It's been a favorite of mine since back then.
The first version below was recorded in a gymnasium (lots of natural reverb) with a single microphone. I love the endless quality of this version, especially with Kim's fiddle playing. It's like the tune is infinitely long and we just get this small 2-minute window to catch a glimpse as it goes by. The 2nd and 3rd versions were recorded at home.
