We really screwed up last month, listing Taj Mahal’s show at Asylum (121 Center St., Portland) as happening July 23 when it’s actually scheduled for today. If you’ve been standing outside Asylum for a month wondering when the legendary bluesman is gonna arrive, we’re very sorry. We promise he’s really supposed to play tonight at 9 p.m., with Maine Marimba Ensemble opening. Tix: still $39 (18+). 772-8274. portlandasylum.com.
