When Sia sang her tremendous “Chandelier” on Ellen, she performed with her back to the audience and brought along 11-year-old Maddie Ziegler to recreate her routine from the song’s video while wearing a blonde wig shaped like Sia’s trademark haircut. She took that concept to a spectacular new level during last night’s Trailblazers special on Logo TV. Sia once again wailed away with her back to the crowd, but this time she was backed by the NYC Gay Men’s Chorus — all of whom were wearing yellow robes and Sia wigs — and a shirtless mustachioed man (also in a Sia wig) handled the wild dance routine. Watch the eye-catching performance below.

Sia’s 1000 Forms Of Fear is out 7/8 on RCA/Monkey Puzzle.
