Most Chicagoans think that once Labor Day passes, that's it for the festivals in Grant Park. Not so: there's still Celtic Fest yet to go, this Saturday and Sunday. Dolores O'Riordan, formerly of the Cranberries, headlines at the Petrillo Music Shell along with Lúnasa and Jon Langford on Sept. 15, and Damien Dempsey, Searson and Salsa Celtica perform on Sept. 16 — and those are just the highlights of a festival featuring national and international musicians representing all Celtic nations on nine stages, all for free. Head on down and dance awhile!
Celtic Fest, Sept. 15-16
Grant Park, Columbus Drive and Monroe Street, Chicago
