Mardi Gras occurs at USF. The concerts usually occur right after the Mardi Gras parade. The parade begins at closing and takes about 20-30 minutes to circle the park.
The Sat. nite concerts start a few mins. after the Parade, & the "house band" plays before the Parade on all other days (days there is a Parade).
Those are good shows too if you get to catch one.
