During the '60s, the blues were rediscovered by a new generation of young listeners. A number of older country-blues artists, like Son House and Furry Lewis, experienced a dramatic upsurge in popularity, as their older records became popular and they became in-demand performers. Many of these artists recorded prolifically during the Blues Revival of the '60s, and these records became quite popular. At times, these recordings were the only opportunity the musicians had to record extensively since the '20s or '30s (or were the only chance to record at all).
