John Hartford didn't just bite the hand that fed him; he made it a full-course meal. After Glen Campbell rode Hartford's "Gentle on My Mind" to the top of the charts, Hartford was secure enough to stick his tongue out at the Nashville establishment. His songs offer an almost unparalleled blend of sardonicism and sincerity, a silliness tempered by a respect for musical tradition and beautiful melody. And despite his irreverence, he attracted the best pickers in the business. Norman Blake, Tut Taylor, Vassar Clements, and Randy Scruggs accompany him on this 1971 "newgrass" gem, a spontaneous album that was recorded live in the studio without any arrangements whatsoever. Delicious instrumentals stand by novelties about sex ("Boogie") and drugs ("Holding"), and semiserious diatribes ("Tear Down the Grand Ole Opry") live next to old-time gospel harmonies ("Turn Your Radio On"). Somehow, Aereo-Plain manages to be deeply cynical and emotionally uplifting at the same time. --Marc Greilsamer
