Mushroomhead

Thanks partly to the contributions of Ryan “Dr. F” Farrell, a longtime band member who recently went back to school to get his masters in composition, the latest Mushroomhead album, Call the Devil, features some carefully crafted carnival-like moments in tracks such as "UIOP (A Final Reprieve)." Expect to hear it when the local group brings its annual Halloween show back to the Agora. Upon a Burning Body, There Is No Us, Mind Incision, Bittersweet Revenge and Psycho open. Doors are at 5:30 p.m.
