Lafayette’s homegrown reggae troupe, True Man Posse, lights up Downtown Alive tonight, starting at 5:30 p.m. at Parc Sans Souci. It’s the free spring concert series’ last scheduled show, but DTA will be offering up an encore of sorts next Friday when Lafayette’s Bayou Boys make up for their rained-out show earlier in the season. Remember to support the cause and leave your ice chests at home.
