Tues. April 20 -- Barking New Jersey humpa-humpers Overkill, fine, Dutch thrash-rattlers God Dethroned, fine, but for me the main attraction is Poland's Vader, whose pomp is more classical and whose melodic darkness spans a greater range of metal.

Tues. April 20 -- California EAR Unit performs Ulrich Krieger's electro-acoustic arrangement of Lou Reed's "Metal Machine Music." I love the 1974 original primarily as a funny conceptual-art joke and a way of punishing unfriendly neighbors. They say Lou likes this version; I'm not sure whether that's a recommendation or not, but anything that makes him a buck is okay. At REDCAT, 631 W. Second St., downtown 90012; 8:30pm; $20; www.redcat.org.
