Get a big day out mug for your friend Paul.
The biggest, and best music festival in Australia. It tours Australia and New Zealand every year, and has some of the best music acts around. This year was the best ive been to, with The Killers, My Chemical Romance, Tool, Jet, Muse, Evermore, Eskimo Joe, The Presets, Lily Allen, Hot Chip and Sick Puppies.
The day runs from 10am till late, and features about 5 stages, so theres always someone good to listen to.
Plus, theres awesome rides and stuff if you get tired of the mosh environment!
Best day of the year!
I listened to The Killers from the top of the ferris wheel at Big day out '07. It was mad!
