One indication of renown is the reduction of your name to an acronym; so when we saw "DTA!" in the subject line, we knew that Downtown Alive! had arrived. The popular outdoor music event is back this fall with music and dancing for the entire family. DTA! is amping up the buzz, keeping info on the musical lineup close to the chest. At the time of publication, only performance dates had been anounced. But check out the website to discover what will, no doubt, be a stellar lineup to celebrate cooler weather. 5:30 p.m. for food and beverage concessions with musical performances from 6 pm—8:30 pm. September 13, 20, and 27 and October 4. Parc International and Parc Sans Souci in downtown Lafayette. Free. downtownlafayette.org.
