Folk rock band Rusty Belle will be taking the stage at New York City’s The Living Room on Sept. 19 as part of their East Coast tour in support of their latest record. This week marks the release of the Massachusetts-based trio’s third studio album, Common Courtesy, which sticks to their trademark gentle harmonies and imaginative lyrics with a strong bluegrass undertone. The group formed in 2006 and have spent the past several years playing everywhere from festivals to coffee shops, even releasing a live album recorded in their hometown of Northampton last June.
