2 CD Set Contains Previously Unreleased Performances. JESUS ON THE MAINLINE is drawn from two 1971 concerts; April 14th, 1971 in Tacoma, Washington, and November 5th, 1971 at the Gaslight In New York, which would prove to be the final recording of the Delta Blues legend. The bottleneck guitarist was 67 years old when these tracks were recorded and his passion and conviction seem to have strengthened with the years. At this point in McDowell's career he had shifted to playing electric slide guitar. Accompanying McDowell's gruff voice, the guitar often seems to finish the singer's sentences for him; it's like listening to an old married couple.
