Florence + The Machine have debuted a new song.

The indie pop band - fronted by Florence Welch - has unveiled a new track titled 'How Big, How Blue, How Beautiful', which is their first new music since their 2011 album 'Ceremonials'.

The track was uploaded to YouTube on Tuesday (10.02.15) along with a video directed by Tabitha Denholm and Vincent Haycock, which shows the 28-year-old singer dancing in an abandoned room with another version of herself.

The video comes a day after the star hosted a private listening party of the band's third studio album at Les Trois Garçons in Shoreditch, London, where she played new tracks including 'Ship To Wreck', 'Caught', 'Delilah' and 'What Kind Of Man' to pals including The xx, Jessie Ware and Daisy Lowe.

Rumours surrounding the imminent announcement of the highly anticipated album were heightened briefly on Tuesday morning (10.02.15) when iTunes briefly posted a banner welcoming fans to pre-order the album, which would allow for an automatic download of the first single, 'What Kind Of Man', although this has since been taken down.

Florence + The Machine will perform at several festivals this summer including Benicàssim in Spain, Rock Werchter in Belgium and South Side Festival in Germany, while they also have odds of 8/1 to headline the prestigious Glastonbury Festival in west England.
