The sold-out concert for the hip-hop group Macklemore and Ryan Lewis scheduled for Tuesday, April 2, has been postponed due to illness.

The Luther College Student Activities Council-Concerts Committee, which is sponsoring the show, will announce a new Macklemore concert date in the fall of 2013 as soon as possible. Those who purchased tickets through the Luther College Box Office will automatically receive a refund. Ticket purchasers who have not received a refund within two weeks should contact the Box Office at (563) 387-1357.

National recording artist Kelley James, scheduled to open for Macklemore and Ryan Lewis, will perform as scheduled Tuesday at the Luther College Regents Center. No tickets will be necessary. Doors will open at 7 p.m. and the concert will begin at 7:30 p.m.

Ben Haggerty, known as Macklemore, postponed the Tuesday show because of problems with his vocal cords.
