Book excerpt: This compilation of essays takes the study of the blues to a welcome new level. Distinguished scholars and well-established writers from such diverse backgrounds as musicology, anthropology, musicianship, and folklore join together to examine blues as literature, music, personal expression, and cultural product. Ramblin' on My Mind contains pieces on Ella Fitzgerald, Son House, and Robert Johnson; on the styles of vaudeville, solo guitar, and zydeco; on a comparison of blues and African music; on blues nicknames; and on lyric themes of disillusionment. Contributors are Lynn Abbott, James Bennighof, Katharine Cartwright, Andrew M. Cohen, David Evans, Bob Groom, Elliott Hurwitt, Gerhard Kubik, John Minton, Luigi Monge, and Doug Seroff.
