Powered by homemade amps and snarky attitudes, noise rockers Shellac are best experienced live. Whether it’s vocalist-guitarist Steve Albini’s sardonic invective and brutal attacks on his guitar (which he straps onto his belt like a weapon) or his foil, singer-bassist Bob Weston (who welcomes questions from the audience that are usually as mundane as the things Albini condemns), the trio offers no dull moments live. And even if you resist the frontmen’s personas, there’s always drummer Todd Trainer, who looks like a possessed man abusing his kit as a means of exorcism. That actually might be the best sight of all.
