Sia and the NYC Gay Men's Chorus Perform 'Chandelier'

Last night during Logo's inaugural Trailblazers Awards, Sia took the stage to perform her summer hit, "Chandelier."

The singer, who is notoriously media shy, turned her back to the camera letting the New York City Gay Men's Chorus take centerstage. The men -- werking some Sia-inspired blond wigs -- added backing vocals to the song while a performer reinterpreted the music video's dance number.

The ceremony, which set out to honor pioneers in the LGBTQ community, celebrated the achievements of Edith Windsor for helping end DOMA, Jason Collins for being the first out athlete in a major sport, and Orange Is the New Black, which has helped break down barriers for queer and transgender characters on TV.
