The Undergraduate Association (UA) Events Committee has announced Macklemore featuring Ryan Lewis as the headliner for SpringFest 2013, MIT’s annual concert event. The concert will be on April 26 in Johnson, and the opener will be determined in the coming weeks. A survey sent by the committee in the fall showed “overwhelming” support for Macklemore, according to committee member Daniela M. Yuschenkoff ’14. The survey included other artists that, according to Yuschenkoff, were not touring far away or recording at the time of the concert, and also asked students what genres of music they would prefer.
