Standing in for Radio 1 Breakfast Show host Nick Grimshaw (who was at home vocally challenged), Scott Mills announced the new acts that would join the already confirmed Taylor Swift, Florence + the Machine and Years & Years. Muse and Foo Fighters, both of whom are exceptionally busy over festival season, are expected to headline this year's Weekend edition. They will also re-unite at Pinkpop in June and Belgium's Rock Werchter.

'I'm very excited to play', Muse frontman Matt Bellamy told the BBC. 'The last time we played Big Weekend, for us it was a disaster, so I can't wait to make up for it on this performance. I'm really looking forward to coming back and doing a great show.'

It's not clear why the band considered their 2006 appearance at Big Weekend such a fiasco, but then, it was their first live show in two years. Muse will release a brand new album entitled 'Drones' on June 5th 2015, featuring their newest single 'Dead Inside'. 'I'm pretty sure that we may unveil another new song that we will play for the first time which is pretty exciting', Bellamy added.
