Sludge rockers Big Business drop heavy, say again, heavy, stoner and psych rock that's akin to a kick in the nads. With steel toed boots. The Seattle blokes' stints in Melvins, Karp and Murder City Devils have only honed the classic metal guitar bombast. The trio will release its third album, Mind the Drift, next month. In the meantime don't forget the earplugs and the motion sickness patch. There must be something in the waters of the Northwest. With Tweak Bird. $10 advance, under 21, $12. Doors at 8 p.m., show at 9 p.m. Milestone, 3400 Tuckaseegee Rd. www.themilestoneclub.com.
