weekend essentials Sept. 30 to Oct. 3 ON STAGE Saturday night, a group of 38 student writers, directors and actors will gather to create four plays from scratch in 24 hours. Satur- day at 10 p.m., they'll perform their barely rehearsed original pieces for free in Studio One at the Walgreen Drama Center. Base- ment Arts's annual 24 Hour Theatre could make you laugh, cry and who even knows what else!? Come see the creativity 24 hours of stress can produce! ON DISPLAY This Sunday from noon to 5 p.m. is the annual ID Day at the Exhibit Museum of Natural History. Experts will be stationed to iden- tify unknown items, like skulls and pottery shards, that visitors bring in. The museum will also celebrate the first National Fossil Day during this event, though the official day is not until Oct. 13. Admission is free. FILM You thought "Para- normal Activity" was scary? Suit up, guys and gals, and head on down to the Michigan Theater Saturday at 10 p.m. for a spine- chilling screening of Dario Argento's "Sus- pira." This 1977 under- ground classic about a ballerina who attends a boarding school of pure evil has a reputa- tion for being one of the freaky-deekiest movies of all time. CONCERT This Saturday night, the Brooklyn-based sensation Kid Cudi will be throwing down indie hip-hop rhymes at the EMU convoca- tion center as part of his album release tour through the Midwest with special guest PARADIME and Ro- Spit. Tickets are first come, first serve - and they're going fast. Free transportation is provided from the Michigan Union all night. Tickets are $33. i
