The first round of auditions begin on the 15th season of the hit dance competition series SO YOU THINK YOU CAN DANCE, as highly-skilled dancers between the ages of 18 and 30 will showcase their talents in various dance styles, including contemporary, tap, hip-hop, ballroom, animation, breaking and more. Those who are selected to move on to the SYTYCD studio will work with world-renowned choreographers and compete LIVE each week for America's votes in a variety of styles. Contestants will be eliminated weekly until a winner is named on the season finale. Nigel Lythgoe, Mary Murphy and Vanessa Hudgens will return as judges, and the new season will also feature returning host Cat Deeley. Stephen "tWitch" Boss joins the judges in the audition cities.
