1. NME’s official ‘Best British Band’ and headliners Biffy Clyro, tell us what to expect from their performance. “Biffy at our best. We love Reading & Leeds and to be asked to play the festival is such an honour. We plan to play as long as they’ll let us, to try and fit in as much of our 6 albums as possible. There will be bare skin and plenty of sweat, with a chance of tears………..and maybe some fireworks!” Ben Johnston

2. Eminem’s last performance at Leeds Festival was 12 years ago in 2001 when Leeds turned 3 years old, this year Leeds turns 15! The first Leeds Festival was held in 1999 moving to its current home Bramham Park in 2003.

3. Green Day are no strangers to Reading & Leeds Festivals, but the band haven’t played Leeds since 2004 so their return to headline on the Saturday evening will definitely be one to watch.

4. After forming in Leeds at university, Alt-J’s debut appearance at the festival was in 2012 when they played the Festival Republic Stage. After a huge year for the band, the Mercury Music Prize and Ivor Novello winners return to headline the NME/Radio 1 Stage. One of the band’s members, drummer Thom Greene, is actually from Harrogate so just a short drive from the Leeds site.

They have played every music stage at the festival and not only that, they have opened on each of those stages, charting the bands success. The band will be appearing on the Alternative Stage as part of Transgressive and one of the members, Rob, will play in his other project Menace Beach during Dance To The Radio’s Thursday night takeover in Leeds.

7. Man of the moment Jake Bugg takes the leap from the Festival Republic Stage to perform on the NME/Radio 1 Stage, following on from his successes in 2012 which included a Number 1 album, an Ivor Novello nomination and a Best Breakthrough Act accolade.
