Archive.org has an excellent collection of 78 rpm records available in MP3 form. Old-time music doesn’t get much better than the Skillet Lickers. You have to hold your nose to get through the politics of some of their work, but the playing and singing are uniformly excellent.

Their 1929 recording of Soldier’s Joy is brilliant. Riley Puckett was the gold standard for old-timey guitarists. His broken bass lines on this song are quite nice. What really makes the tune, tough, is the heterophonic frenzy of the fiddles, especially when they get to the ‘B’ strain. The fiddlers are playing simultaneous variations of the same core melody. The tension created by the differences in note choice and intonation give the performance an energy that is sorely lacking in the work of many revivalists.

A version of this tune, in slightly altered form, appears on Where You Been So Long?. Our morphine is ten cents cheaper than the Skillet Lickers’.
