Mayfest has signed Chicago hip hop artist Common as its night headliner for Dillo Day, the group announced on its Web site late Monday night.
The other acts scheduled for Dillo Day remain unknown.
The Center for Student Involvement confirmed Thursday that a contract had been sent to the Grammy Award-winning artist.
Mayfest organizers announced early March that Dillo Day would take place May 31, the weekend after its usual date, the Saturday before Memorial Day. The new date allowed organizers to secure big-name acts because many bands schedule concerts for the holiday weekend early on.
