Chris Moyles unveiled the line-up of over 30 UK and international artists who will be playing on the two main stages during his show, with a bit of help from fellow Radio 1 DJ Zane Lowe.
Other artists include Scouting for Girls, Biffy Clyro, JLS, the Lostprophets, Kids in Glass Houses and Marina & The Diamonds.
BBC Radio 1's Big Weekend is the station's flagship event and the UK's biggest free ticketed festival. Around 40,000 fans can enjoy performances from four stages in Vaynol Estate - the Main Stage; the In New Music We Trust Stage; the Outdoor Stage and the BBC Introducing Stage.
For listeners tuning in there will also be exclusive Live Lounge sessions broadcast from backstage.
