DC grad Sarah Mark hits the Top 40 with song 'Tun Up' Posted on July 11, 2016 at 10:03 am. Less than a month after her Durham College (DC) convocation ceremony, Music Business Administration graduate Sarah Mark is certainly making her mark on the Canadian music industry with her hit song, “Tun Up.” The song debuted on June 25 at number 49 on Canada’s Billboard Contemporary Hit Radio Top 40 chart and quickly climbed to a spot in the Top 30. “Tun Up” is getting airtime on popular radio stations across Canada, including Virgin 99.9 in Toronto and Winnipeg, and even caught the attention of TV personality and radio host Ryan Seacrest. When she graduated from DC in June 2016, Mark, an International student from Trinidad and Tobago, also landed a spot on another top list: the President’s Honour Roll, which recognizes students with a cumulative grade point average of 4.0 or greater. The two-year Music Business Administration program prepares students for the competitive music industry. Students develop skills in management, marketing, promotion and small business while learning the essentials of event production, live sound reinforcement, studio operations and media. SHARE:
