Pig Destroyer, Brutal Truth, Repulsion

July 31, Brooklyn Masonic Temple, 317 Clermont Ave. (at Lafayette Ave.), Brooklyn; 8, $25

Here’s a secret about the Masons of Brooklyn: They’ll let anybody in. Of course, when you’re grindcore pioneers Repulsion you have cachet among all the secret societies.Tonight’s show also includes Pig Destroyer and Brutal Truth, two later grindcore groups, and inaugurates the awesome new Blackened Music Series.

Bottom Line: Nothing so brutal or aggressive has come to the Masonic Temple since the last time Gleason’s had a fight night there. Or that time the Masons decided to invade Iraq.
