I've been to a couple (Bloc Party/The XX) and have a couple more good gigs lined up recently. (Future Islands and The Cribs)
I went to watch The XX on Sunday at the Apollo (Manchester) and they were sensational. Jamie XX is a genius and it's refreshing to see such a modest band that don't realise just how good they are.
Jamie XX (who does a lot of solo dance stuff) has about £10k worth of kit kicking around and makes some unreal visuals, sounds etc. For me, they're one of my favourite bands as they bring together the best of modern music production and traditional stuff. But they're just great. 3 albums deep and remarkably consistent. (I'll stop geeking out now!)
