1) Rage against the machine 2008
2) Smashing Pumpkins 2007
3) Metallica 2008
4) Killers 2008 - helped by the incredible run of Foals/Justice/BFMV in the radio 1 tent
5) Razorlight 2007
6) RHCP 2007 ...by a looooong way last, so went to see Hot Hot Heat half way through who were much better
but the subs in 2007 were also better than each of their headliners
we say this every time something like happens, in recent times Slipknot continued, Avenged Sevenfold continued. i feel more bands continue than do not. it will take time. but law of averages show that they are more likely to play again than not.
