Not unlike GWAR, members of Cleveland-based electro-industrial-monster-metal band Mushroomhead lurk behind frightening costumes and junior-high-worthy pseudonyms (Jeffrey Nothing, Skinny, Gravy, and Pig Benis to name a few). A (recently-ended) longtime rivalry with Slipknot (allegedly fueled by the two groups having a bit too much in common) hasn’t kept Mushroomhead from releasing 13 frightening videos and six explosive studio albums leading up to this year’s shocking offering ? Beautiful Stories for Ugly Children. Also on the bill: Final Trigger, Koheleth, and Stygian. $18-$21, doors at 7pm, Backstage Live, 1305 E Houston, frontgatetickets.com.
