STS9 has confirmed two spring dates. The group—who will only play select shows in the coming months—will perform at New Orleans’ River City Ballroom on April 27 during JazzFest. Nodding to their original name, the quintet are billing the show as “a special night of Sector 9.”

STS9 have also added a stop at Rockdale, TX’s Nocturnal Festival on April 28. Like most of the band’s 2012 dates, this performance will be a part of the “Great Cycle Spectacles” series celebrating the changeover of the Mayan calender.
