The Performing Arts Center at Third Street, known better as PAC3, opened in downtown Carbondale in the summer of 2011. The 5,000-square-foot multi-use venue, which holds 365 people for seated events and 541 for unseated general-admission shows, brings in a steady stream of local and touring acts (including rock, bluegrass, folk and jam bands), but it’s also used for community events, nonprofit functions and festivals.
