Singer and songwriter Sean Rowe’s rather astonishing singing voice evokes the sound of the ages. His big rumbling baritone bears traces of John Lee Hooker, Greg Brown, Wilson Pickett, and others, though it is utterly unaffected. Rowe hails from Troy, New York. In his teens he discovered the blues of Muddy Waters and Hooker as well as the soul music of Marvin Gaye and Ray Charles. He began playing guitar and learning songs by virtually every artist he admired — and then some. By the time he began playing the local bar scene at 18, he had amassed enough original and cover material to perform four one-hour sets per night. Sean’s latest album, Madman, found the singer mixing all of these influences, dabbling with pop and bluesy rock along with brooding folk.
