I was there and I definitely recall being on a train back from IFEMA to the city centre after the festival full of these Scottish blokes who'd been waiting for Massive Attack only for them to never turn up going "f**k Massive Attack bunch of w*nkers and posh c**ts" for pretty much the whole train ride.
Take it they weren't impressed by saying the sound bleed issue from Franz Ferdinand was too much. Not that I was there for it given I had been at Franz and was amused by Alex Kapranos instigating an invasion of the VIP block out front.
So it's also there, I went in to that stage for Goat Girl and there was a little sound crossover but not the worst I've ever heard.
