No petulant, open-mic warbler or girly pop tart, the Remnants' smoldering soulstress, Cynthia Duvall, is, ironically, responsible for a major part of the Broward quartet's balls-out attitude. Think of Duvall as the ass-kicking, sass-spewing, rock-star love child Janis and Iggy never had. With one of the hardest-working bands in South Florida, she, along with the rest of the Remnants (guitarist Jim Potts, bassist Dominic Siriani, and drummer Russ Moore), has rattled windows in venues from West Palm to Weston and left crowds panting with rock 'n' roll fever in her wake. Warning: The Remnants are not a subtle band. Check out Duvall on the band's six-song EP or, better yet, catch her belting it out live. You'll be glad you did, if you make it home in one piece.
