I'm going to see Radiohead one of the nights we're there, at a big outdoor park so that will be good, apart from that just chillin out.
Also just saw that theres an exhibition of Stanley Donwood...

But don't know if I'll bother, probably just be wasted, think I'll steer clear of the mushies as well!
