Host Tati Amare talked to Derek Hough, a judge from World of Dance, about how dance is helping people through tough times. Each season the World of Dance competition heats up with even more impressive dancers. Derek says this leads him to believe that dance is ever evolving and getting better. Because World of Dance is open to all ages and performers the show gets amazingly talented dancers from everywhere. Season 4 of World of Dance premieres Tuesday, May 26th at 10 p.m. on Local 4.
