Never been to a bad one. I saw Bryan Adams years ago at an outdoor festival and the wind was awful so they couldn't have the sound systems where they wanted, but where we were was still amazing. A lot of other people complained about it though so it depended where you were.
I know I'll miss someone somehow but other acts I've seen and loved so far over the years (some may age me lol) have been: OTT, Mumford and Sons, The View, Stereophonics, My Chemical Romance, HIM, [spunge], Biffy Clyro, Hugh Jackman, twenty one pilots, Kula Shaker, and Alkaline Trio (when I was 6 months pregnant with my eldest).
If you forced me to choose a favourite I would be torn between Biffy, Mumford and twenty one pilots tbh. And all for different reasons.
I'm going to Radio One's Big Weekend on the Saturday this year, I'm literally only going to see 30 Seconds to Mars but knowing me I'll also be bopping away to the Jonas Brothers and The 1975, and enjoying many other acts I've never even heard of before.
I just love live music no matter what it is. I was a photographer for a local blues festival even though it wasn't originally my sort of thing, and I found some great local and not so local smaller acts through that too. One of them actually introduced me and DH to each other. 😃
