Bastille are choosing from 25 songs for their new album.
The 'Pompeii' hitmakers are busy putting together their follow up record to 2013's 'Bad Blood' and have admitted they're taking their time as what songs they choose will determine what genre the album is.
Frontman Dan Smith said: "We've just been very busy writing and recording a lot of new music.
"We've written a whole album, we've got 25 songs give or take.
"We're kind of just finishing everything off an finessing what tunes are gonna make it cause it could literally be one of three or four very different records, so we're just figuring out which one it is."
The band - which is also made up of Chris 'Woody' Wood, William Farquarson and Kyle Simmons - have experimented with different styles of music this time around.
Dan told Billboard magazine: "When we started the album, this is more than a year ago, it was alternative R&B, a lot more electronic, then we went down a heavier rock route as well, then we almost came full circle back around to what we did the first record, more cinematic, then we did a load of horns. So it could be a lot of different things. But we just want the songs to be good and memorable and we want the album to be fucking interesting and a good progression from the last record, something that we're proud of."
And while they are still putting the finishing touches on their latest creation, they've already decided on a title.
He added: "We have the name of it in our heads, we've got the concept, I think thematically, in the last few months, it really came together and that's nice 'cause a lot of the songs are quite narrative."
