After kicking around in various Columbus metal bands over the years, most recently Sin Nombre, Bob Brinkman came to a simple but powerful conclusion: Slower is heavier.

"When you lag the beats a little bit," Brinkman said, "it's just so much heavier than fast music could ever be."

About two years ago Brinkman, a bassist, set about seeing how slow and low he could go. He recruited Locusta bassist Scott Hyatt to double the low-end chug. When Brinkman's high school bandmate Cory Barnt moved from Lima to man the drum kit, they christened the sludgy new ensemble Bridesmaid.

After half a year of rehearsals, they played their first show in November 2009 and haven't ceased a rigorous schedule since, touring every weekend they can swing it.

They've also been hitting the studio. A five-track collection of dark dirges saw release on CD last summer, followed by a cassette on the Bastard Sloth label. Friday at Carabar they'll release their next record, a split 7-inch with Sun Splitter, a Chicago group featuring several of Brinkman's former bandmates.

Those attending the release show should be prepared for Bridesmaid's other defining characteristic: They turn up the volume to a violent extent.

"The room shakes when we're playing," Brinkman said.

Thus, the band keeps a steady supply of disposable earplugs on hand, which they wear for every practice and show with a few exceptions.

"I'm a sweaty dude, so sometimes mine just fall out when I headbang," Brinkman said.

Fortunately for listeners, Bridesmaid is kind enough to distribute the earplugs for free at their merch table.

"We don't want people to go deaf," Barnt said.

Hyatt chimed in: "We don't?"
