Singer-songwriter Grace Potter initially emerged out of St. Lawrence University in upstate New York and quickly found a foothold within the jam band scene. It wasn't long, however, before Potter started to appeal to country fans, too. Her 2007 record, This is Somewhere, resonated with country singers, and Potter has said that Little Big Town, Lady Antebellum, Keith Urban and Taylor Swift all started listening to her albums. The singer-songwriter performs tonight at 7 at the Agora Theatre as she brings her Mother Road tour to town.
