Dex, who was formerly half of the Flat Duo Jets, and his sister, Sara Romweber, formed The Dex Romweber Duo in 2007. However, Dex Romweber has been performing for almost a quarter century, and has even inspired Jack White to make music. The band has released three albums—2009’s Ruins Of Berlin, 2010’s Live At Third Man and 2011’s Is That You In The Blue?—and will release another this year. The duo’s music can be described as Johnny Cash-like American rock. They will be performing at the Mercury Lounge in NYC on March 23.
