"Yeah, go see them. I would go to motörhead, maybe megadeath and slayer. I've checked out the last few years of this festival and i quite like some of the bands included actually, so it's definitely worth it.
"Also for anyone who doesn't know, there are day tickets available. Although they don't seem to announce which day Weezer is playing, if you don't like the bands/don't fancy camping this is probably your best option."
