Chicago DJ duo Flosstradamus will play two half-hour sets at this Saturday’s Dillo Day, Mayfest announced Tuesday.

The tandem — Josh Young and Curt Cameruci — will perform before and after Broken Social Scene, which is due to take the stage at 5:30 p.m.

The duo makes “basically party dance music, so it will provide entertainment for set breaks,” Mayfest co-chair Ben Stix said, “so people can dance while we change the sets for Broken Social Scene and for The Cool Kids.”
