by Richie UnterbergerAlthough Hammond had already recorded electric material, he went back to a solo acoustic format for his fourth album, accompanying himself on guitar and harmonica on faithful interpretations of standards by Robert Johnson, Blind Willie McTell, John Lee Hooker, Sleepy John Estes, Jimmy Reed, Willie Dixon, and Bo Diddley. If it sounds a bit unimaginative and routine today, one has to remember that the general listening audience was much less aware of these artists and songs in the mid-'60s. Hammond did a commendable job of rendering them here, with fine guitar work and vocals that were a considerable improvement over his earliest efforts.
