Where is it? Richfield Avenue, Reading, Berkshire, and Bramham Park in Leeds
When is it? 27-29 August 2004
Who's gonna be there? The Darkness, The White Stripes, 50 Cent, Ash, Lostprophets, Franz Ferdinand and The Hives for starters.
What's it like? Reading festival is all about rock. You won't find many cheesey pop bands at this festival. Cue loads of rock star antics, like when Green Day trashed their drum kit and set fire to the stage at the start of 2001's event.
Although it's called Reading, there's also a sister event at Leeds. Both have three stages - the main stage, the evening session stage and the dance stage. There's normally about 55,000 people there each day.
