Jennifer Nettles and Carly Hughes come from two different worlds. Hughes is a Broadway baby, having appeared in Pippin and Beautiful — The Carole King Musical, among other shows. Nettles is a country music star, a three-time Grammy-winning singer-songwriter better known as half of the duo Sugarland. Together they are Broadway's latest Velma (Hughes) and Roxie (Nettles) in the long-running musical Chicago, featuring the new duo through March 29. TheaterMania caught up with the pair in rehearsal as they offered a sneak peek of their vocal pyrotechnics and a few words about how much playing these roles mean to them.
