They'll also be performing on the Lock Up stage as The Bronx.
Reading & Leeds Festival 2015's ever expanding line-up continues to grow with yet more acts announced to appear across the many stages; some of which are well-established, and some up-and-coming, but all definitely worth experiencing this year.
Kicking off proceedings, Mariachi el Bronx will be bringing a little Mexican spirit to the UK festival - which will be just as well if the English weather lets us down come August. They'll be joining headliners Metallica, Mumford & Sons and The Libertines, plus many more top billing artists such as Kendrick Lamar, Alt J and Bring Me The Horizon.
The popstar will be joined by headliners Rudimental and McBusted from August 28th - 30th.
None other than Canadian heartthrob Justin Bieber will be headlining Birmingham's Fusion Festival this Summer, performing for the event's first ever Friday opening on August 28th 2015 as it becomes a 3-day event for the very first time.
Fusion Festival with Vimto will mark an exclusive UK performance for the award-winning, record-breaking popstar, whose last performance in the country was in 2013 as part of his Believe World Tour. He'll be facing 50,000 festival goers at Cofton Park in Birmingham, alongside Saturday and Sunday's respective headliners Rudimental and McBusted.
