Friday mornings lost a lot of their pep last summer when Pete Wilson took a hiatus from his long-running 91 Rock radio show, two celebratory hours of postwar piano boogie and rollicking jump blues. As of last month, Wilson is back in his 8 a.m. drive-time slot on Vanderbilt's college station—a boon to everyone sick of canned zoo crews and 10-song playlists. The avuncular host shares his fathomless knowledge of obscure labels, session men and singles while hipping listeners to some of the most high-spirited music ever recorded. Here clown prince Louis Jordan is king, Big Mama Thornton is queen, and the royal buffet includes manic helpings of "Buzzard Pie" and "Alligator Meat." Listen once, and you'll join the growing number of listeners for whom the show is a secret handshake. —JIM RIDLEY
