The Manchester four-piece will perform during the intimate festival at Bushmills Distillery on 12 June, following in the footsteps of previous headliners such as Snow Patrol, Jake Bugg and Of Monsters And Men.In the past the Girls hitmakers have supported The Rolling Stones and Muse and are about to embark on a world tour that will take them to Australia, Japan and the US.Lead singer, Matthew Healy, said: "We've never played a show in a distillery before so it's a first for us. "We've gigged all over the place but to play a festival like this, in a setting as unique as this, will be pretty special."This year the festival will see 700 music fans invited to the distillery on 11 and 12 June to witness emerging and iconic artists sharing the stage for a series of intimate gigs.Tickets are not available for general release but fans can enter a draw via the Bushmills Facebook page from Monday 17 March.Meanwhile to celebrate Bushmill's Live 2014, a 10ft set of headphones have been crafted from age-old whiskey barrels to form the centrepiece at the gigs.The fully functioning phones will blast out the songs played during a two-day music festival.Master distiller at Bushmills, Colum Egan, said: "We're looking forward to throwing open the doors of the distillery and welcoming friends, old and new, to come and enjoy the handcrafted whiskey and music on offer at Bushmills Live 2014."It really is a highpoint of our year."He added: "We'll be announcing the full line-up soon and I can promise you some spectacular surprises as well as some good friends returning."
