It’s appropriate that Boz Scaggs’ new album is Out of the Blues, since the blues is what first sparked his five-decade musical career. Born William Royce Scaggs, he grew up in Oklahoma and Texas, where he spent his teenage years immersed in the blues, R&B, and early rock ‘n’ roll. After several years as a journeyman musician, he spent time traveling in Europe, the Middle East, and Asia, eventually settling in Stockholm, where he recorded the album Boz.
