WILLIAMSBURG: It’s been a bit of a rough year for M.I.A., between Trufflegate and her much-maligned HARD Fest performance. Tonight, she’s going to try to earn some goodwill back with a free (!) show at Brooklyn Bowl. The gig is meant to make up for June’s HARD Fest debacle, which saw her set cut short by lightning amid sound problems, but tickets are first come, first served, so anyone who’s willing to fight the crowds is welcome to attend. The line starts at 7 (and don’t bother showing up the night before – Brooklyn Bowl isn’t letting people form a line until then), and doors are at 9:30.
