Previously, the casino booked shows through a talent buyer out of Los Angeles, but now is hoping to take advantage of bands’ tour schedules, often booked through Live Nation, said Matt Gibson, director of vibe at the casino, who is responsible for entertainment, venues and promotion. This year, the shows were booked through Live Nation, the massive global entertainment company that is the subject of an antitrust investigation by the Justice Department. This is the twelfth year of the Pepsi Outdoor Summer Concert series at BECU Live, the 5,000-seat outdoor arena at Northern Quest. Northern Quest Resort and Casino announced the first six shows of its summer concert series lineup on Monday, including Dan + Shay and Jason Mraz.
