The Top 20 performed on So You Think You Can Dance last night, a chance to show off their excellence in their own forms. After a harrowing time during Vegas week, these 20 proved that they outshone their peers, and had what it takes to get to the live show. SYTYCD judges Nigel Lythgoe, Jason Derulo, and Paula Abdul had the most difficult job of choosing the best of the best, with some assistance from Team Street mentor Stephen “tWitch” Boss (most recently of Magic Mike XXL) and Team Stage mentor Travis Wall. Host Cat Deeley kept everyones spirits up during the previous episodes, but returned to the spotlight to look lovely, and do what she does best.

“Welcome… to So You Think You Can Dance!”

This is it! The last round of choreography before the top 20 are chosen. SYTYCD started out with 105 street dancers and 114 stage dancers in last week’s Las Vegas callbacks, vying for a spot on Stephen “tWitch” Boss‘s Team Street or Travis Wall‘s Team Stage. And it was tough – tough to perform, and tough to judge. But judged they were, with constructive criticism that they would hopefully take into account for their future dance careers, doled out by Nigel Lythgoe, Jason Derulo, and Paula Abdul.

Spoiler alert! The SYTYCD Top 20 is revealed below. Do not continue if you haven’t watched the episode!

Auditions are over on So You Think You Can Dance, and it’s time for Vegas! SYTYCD brings these excellent dancers to meet their mentors in Sin City. Can they master choreography? Team Street will meet their mentor, Stephen “tWitch” Boss, and will learn choreograhy from masters Dave Scott, Tabatha and Napoleon, and award winning choreographer Jamal Sims. Team Stage led by Travis Wall will learn contemporary choreography from Wall, jazz from Sonya Tayeh, and Broadway with another award winner, Josh Bergasse.

My favorite reality competition of all time, So You Think You Can Dance, SYTYCD for short, returned for season 12 tonight, with new judges and a new format. The first episode takes us through the auditions in Memphis and Dallas. Contestants were fighting for their ticket to Vegas on Travis Wall‘s Team Stage, or Stephen “tWitch” Boss‘s Team Street.
