Who says the weekend ends on Monday morning? For the last four years, Monday nights have been an assault on the senses at Pehrspace, and the man behind the mayhem is Sean Carnage. Carnage is king of the far-out, curating this musical magnet for all things freaky, and pulling in the most experimental and off-center bands for a spazzfest that should be preserved in the Natural History Museum. Bands like HEALTH, Monotonix and Dan Deacon have made visits to Carnage's Monday night special, whose show is like a halfway house for underage groups and DIY weirdos who have nowhere else to go. Sometimes ear-splitting, sometimes genius, a night with Carnage is an unforgettable and always interesting affair. 325 Glendale Blvd., Echo Park. (213) 483-PEHR, pehrspace.org. Mon., 9 p.m.-1 a.m.
