An unexpected surprise for fans of progressive pop! Big Freedia is the latest contributor to Adult Swim's Singles Series, remixing Sia's "Eye of the Needle." If you're unaware, Freedia is the queen of bounce music, and Sia is the Australian genius behind the unavoidable "Chandelier." 

The song usually sounds, you know, like a Sia song, but here it gets a high energy, spastic makeover. 

Freedia laces the tracks with some of her own quick-spittin' vocals. Listen to it above, then click through our Sia fashion gallery, take our Big Freedia superfan quiz then test your knowledge of bounce music here.
