Adelaide Big Day Out. We were staying in the same hotel as other artists and I came downstaris to go to the after party and a big crowd was surrounding Aracde Fire and Bjork at the grand piano in the restaurant of the hotel. They were doing old show tunes and everyone was singing along. The lead singer of Arcade Fire was playing piano and everyone was singing along. I recall Buddy Holly's 'Everyday It's Getting Closer', a couple of ABBA songs and some John Lennon, it was very cool. Favourite festivals moments though are just when it's a good show with good reactions, where you don't have to think too much on stage and lose yourself.
Ideal Lineup? I'd have bands that would never be seen on the same stage because they've long since broken up or died, I'd have Blur opening the festival followed by the Smiths who would reform for my music festival, and At The Drive In would finish the day just when I was drunk enough to dance like they can.
Fave artist you've seen at a Music Festival? Rage Against The Machine. Also, Brand New who are a vastly under rated band from New York that played at Big Day Out. I saw them pretty much without fail at every Big Day Out and they were astounding, and to use the the cliche, quite inspiring. I've ripped off many of their moves since then!
Tips for attending Music Festivals Don't break your neck. Don't worry too much about getting to the front for every band you want to see. It's probably better to pick 4 or so that you can really absorb as opposed to having cursory glances at every one. It's like any 'day out' it's best to pace yourself, don't go mental and try to see everything, relax and take it all in.
