From his early West Coast rock and soul bands, through his smooth '70s Hollywood years with hits like “Lowdown” and “Lido Shuffle,” to his more recent explorations in R&B, jazz and the Great American Songbook, the versatile singer/songwriter/guitarist has created a highly personal, unfailingly soulful repertoire. The latest edition, Out of the Blues, finds Scaggs, born in Ohio and raised in Texas and Oklahoma, reconnecting with his earliest musical loves.
