Those of you who don't like fake blood (and other bodily fluids), should stay away from the front rows at a Gwar concert. The monster shock rock clan is known for splattering the crowd with its "juices" during its raunchy, over-the-top performances. The group also picks celebrities and other figures from the news to mock onstage. It's all pretty entertaining, that is until a shirt gets ruined. With The Casualties, Infernaeon and Mobile Deathcamp. $20-$23. 6:30 p.m. Amos' Southend, 1423 South Tryon St. 704-377-6874. www.amossouthend.com.
