That isn't the side of the festival that you see on TV though. It's subjective of course but there are much better festivals to go to then Glastonbury. I'm sure if I went there then I'd find something to listen to I'd like but it wouldn't be the headline acts this year for sure.
I know you go to quite a few gigs from relatively obscure and unknown artists and to be fair I think that's where most of the quality is these days. I knew it would be a provocative post as commerical music is made to appeal to as many people as possible. So no doubt more people here and anywhere will love the lineup then not. Peronsally I just prefer to watch musicians with more talent than Liam Gallagher on tamborine or Janet Jackson miming lol.
I've seen quite a few metal acts live in the last month or so: Disturbed at Ally Pally, Loads at Download festival a couple of weeks ago, Tool and Dream Theater being pretty stand out acts. I actually went to see a small act called "Toska" who you may know as I believe they are actually from Brighton who were cool. (Shame they only played a 25minute set though.) So 100% I understand your comment about other great acts across the festival. I did Metallica at Twickenham week before last too.
I have a very wide taste in music though, metal is actually something I've only really got into in the last few years. Perhaps you can highlight where the quality is in the Glastonbury Lineup that I'm missing and I'll give it a listen if I'm not familiar with it as I always like to try out new stuff. With the exception of a couple of acts I think are ok there is very little that jumped out at me as a "wow, need to listen to that."
