Undergrad Alex Preston brought a little star power to the UNH Whittemore Arena on Saturday, May 10, putting on a free concert for a near-capacity crowd. A top-three finalist on this season’s American Idol, the Mont Vernon native put his plans to earn a business and premed degree on hold to pursue his musical ambitions, opening for The Backstreet Boys, Gavin Degraw, and Of Monsters and Men last summer before auditioning for Idol at his father’s suggestion in the fall. With a shot at the Idol title May 21, Preston hit his hometown and then Durham before jetting back to Hollywood for the final two weeks of the show. Not that UNH has necessarily seen the last of him. “I am definitely coming back to school at some point,” he says.
