While you were having a mini-nap at your desk, this year's musical heavyweights made some major announcements. Firstly, Arcade Fire are going to be headlining Glastonbury, closing on the Pyramid Stage on the Friday night. Whether you're drowning in mud at the festival or watching from the comfort of your sofa, we think it's gonna be a pretty amazing set. Secondly, everyone's favourite French robots Daft Punk announced they're going to be performing at the Grammys on 26 January, where they've been nominated for four awards including Album of the Year. This is going to be extra special as it's the first time the duo have played new material live. Bring on 2014.
