It’s not every day you get to watch a rock concert and a B-movie at the same time. But that’s the charm of Midtown’s Plaza Theatre, which at 9:15 p.m. tonight screens Roger Corman’s X—THE MAN WITH X-RAY EYES, while the seminal art-punk underground ensemble PERE UBU, one of the most influential bands of the punk era, performs its soundtrack for the film live in the theater. Tickets are $15. 404-873-1939. www.plazaatlanta.com.
