Also featuring Grouse Party DJs. From psychedelic jazz-hop to soul-quaking booty shaking, this blistering double headliner is set to free minds and bounce behinds.

Seattle-based THEESatisfaction are Stasia Irons and Catherine Harris-White, and right now they're the hottest thing in psychedelic-feminist-R&B-funk-rap. Mining the sounds of the past for their decidedly futuristic grooves, THEESatisfaction sound familiar and strange all at once, an irrepressible mix of jazzed-out funk, upbeat political commentary and dancefloor-ready rhythms, tied together by Iron and Harris-White's soulful vocal harmonies. Touring on the back of their debut album awE naturalE, THEESatisfaction make their Australian debut at Melbourne Festival, and - make no mistake - they come ready to get down.

Appearing alongside THEESatisfaction is none other than the one, the only, the majestic, the magnificent Big Freedia, the Queen Diva.

A take-no-prisoners, six-foot (seven in heels) transgender 'sissy bounce' MC from New Orleans, Big Freedia has been taking the sweat-drenched gospel of booty shaking to the four corners of the globe for over a decade. With hyperactive flow, frenetic beats, a powerhouse dance posse and a live show that has to be seen to be believed - her song 'Azz Everywhere' describes it well - Big Freedia and The Divas have one mission and one mission only: making you shake your ass like you've never shaken it before.

Keeping things flowing between acts will be Grouse DJs, resident party-smashers from Grouse Party, Melbourne's favourite monthly queer-friendly free-for-all.
