Go behind the scenes-and “underground”-for a very special 1st Thursday this month. In addition to checking out all the fine new art on display in our city, you’ll be able to explore the Granada Theatre’s all-new basement and dressing rooms, sample fine wines, and preview the provocative art of Jana Zimmer, honoring the holocaust victims of the Nazi concentration camp Terezin. Check it out on Thursday, May 7, from 5-8 p.m., at the Granada Theatre (1214 State St.). Free. Call 899-2222.
