So thriving is the Plaza District, all it needs now is an iron lung. Perhaps it will settle for the band My Iron Lung, touring with like-minded experimental-hardcore act Troubled Coast. The groups will play at 7 p.m. Monday at Bad Granny’s Bazaar, 1759 N.W. 16th, alongside spoken-word artist Trey the Ruler, metro-based Our Sky Is Falling and Norman hip-hoppers Dare We Say, Pioneers. Tickets are $6. Call 528-4585.
