New York’s Coheed and Cambria and their everything-but-the kitchen-sink offerings are indicative of the new-school predisposition for pluralism. Whereas most fizzle and deteriorate trying to force square pegs into round holes, this quintet of all things rock manages not to be crushed under the weight of its numerous influences. That said, it’s a little too perfect for my tastes with a squeaky clean sound that seems prepackaged. And I find singer Claudio Paul Sanchez’s desperate earnestness to be just slightly less appealing than prolonged prostate exams. But the group’s panty-moistening sound continues be a big hit with post-adolescent crowd, so if you have a hankering for polished alternative rock, this should please you. Coheed and Cambria plays Friday, Nov. 8, at the National with Balance and Composure and the Mighty. Doors open at 6 p.m. Tickets are $25 in advance and $28 at the door. thenationalva.com.
