Fri., April 12, Kill the Precedent

Blue Lamp, 8:30 p.m., $10

Kill the Precedent shares abrasive, aggressive rock synchronized to visually transfixing slide shows displaying random imagery during live performances. The Sacramento band's been busy recently, readying to release a new album, Dialogues With the Dead, this summer. On Friday, the group—along with Black Mackerel and Murderlicious—is playing a fundraising gig called the Tricia Duncan Benefit Show. It's a raffle, baked-goods sale and a night full of music, with all proceeds going toward their friend, Duncan, who is recovering from a traumatic head injury. Witness the charitable sides of these local metal, hardcore and industrial-punk musicians. 1400 Alhambra Boulevard,
