Alton Jay Rubin was born in 1932, in Louisiana, and from an early age began to hone his musical ability. A talented accordion player and zydeco singer (combining blues and R&B, zydeco originated in Louisiana), his teenage years saw him performing at clubs and parties. By the 1950s, using the stage name Rockin’ Dopsie, Rubin was attracting attention from local labels. In the following four decades Rockin’ Dopsie became a major presence in the genre, appearing in songs by Bob Dylan and Paul Simon, among others. After Rubin’s death in 1993, it was up to his son, David, to carry on the Rockin’ Dopsie legacy. And indeed he has. Under the monicker Rockin’ Dopsie Jr., David and his accompanying band, the Zydeco Twisters, have worked with Beyoncé and John Fogerty as well as Dylan and Simon. Their sound perfectly captures the festive essence of New Orleans. A new “soul-stirring, body-moving” studio album by Dopsie Jr. and company is out this August. —Jack Sullivan
