How big?

Three words.
Big. Day. Out.
Yes, that's right, the one day of the year when thousands (40,000, to be precise) of Perth music lovers get together for a day of fantastic music, great atmosphere and (mostly) cool people.
My surprise band on the day was The Vines. I myself am not a massive Vines fan, however their live performance blew me away. Lead singer Craig Nichols' prolonged screams were awe-inspiring. The band was tight and a hell of a lot heavier than i thought they'd be - in all, they blew me away.
A couple of bands i didn't expect to see but ended up seeing anyway were Sleepy Jackson - as expected, entertaining and musically luscious at the same time - and a Liverpudlian by the name of John Cooper Clarke. John Copper Clarke graced the stage at the Lilyworld and proceeded to entertain the crowd with a variety of poems, limericks and one-liners. He had a loud Jet (playing on the nearby main stage) to compete with and did quite well, but lost me when he forgot the words to one of his poems and started to read them from a file he had nearby. Other than that, it was a nice diversion from the music.
As for the rest, well, Tool, Muse and The Killers were absolutely brilliant. To have a blockbuster lineup including those three bands and see them all within a few hours of each other was unreal. They were all amazing, but Muse was by far my favourite. The Killers played an absolute blockbuster of a set and Tool were as tight as a (insert inappropriate metaphor here).
They could do no wrong.
All in all, a great day was had by all and now it's only 363 days to the next one... oh... :(
