Also heaps of Aussie bands here and there, such as Dungeon at least 6 times (including once in Belgium in a crowd of about 15 people!), Vanishing Point, Mortification, Damaged, The Shine, Enter Twilight, Anarion, Temtris (who were fantastic, I would love to see them again), etc, and non metal Aussie bands like Powderfinger, The John Butler Trio, Grinspoon, etc.
To make this more interesting, I will try pick a top 5. Too hard to put them in an order, so top 5 in no particular order!
Anthrax - amazing energy, unmatched by anyone else I have seen, and I am not even a huge fan.
The Tea Party - Brilliant band, awesome set with great covers and simply a great sound. Awesome musos.
Megadeth - FAR better at Graspop (much unlike System Of A Down and Slipknot), best energy I have experienced from a gig, until Anthrax the next night.
Within Temptation - Impressive live show, HUGE sound, played a good setlist with lots from their latest and best album. Great spectacle. Can't wait to get the DVD from that tour, and to see them on the next one.
Iron Maiden - Iron Maiden, enough said. I would have prefered to see them on a normal tour and not on the Early Days tour, but I still really enjoyed the set.
Others that would have been awesome under better circumstances (such as at night and not day, longer set, etc)
Soilwork - great, but not appropriate for 11am in the daylight!
Grave Digger - set was WAY too short, especially after seeing their 2 and a half hour DVD, but festival rules are festival rules.
Kamelot - had I seen the whole set I would have enjoyed them heaps!
Dream Theater - playing stuff from a brand new album that no one had heard was a disadvantage. It had been out only one or two weeks.
Dio - shitty setlist, made for major disappointment. You aren't given much time at a festival, don't waste it with wanky guitar and drum solos that sound lame wedged between sets from Malmsteen and Dream Theater!! Still great, but not awesome like it should have been.
Some of my favourite gig moments:
Amon Amarth's stage presence. Brutal. The syncronized windmills during Pursuit Of Vikings looked so cool, and finishing with Death In Fire was MAGIC!
Kamelot closing with March Of Mephisto. The crowd chanting along to the march with fists in the air was so metal, I loved it.
Iron Maiden's Revelations was amazing, really like being inside the Live After Death album.
Metallica coming on stage to The Ecstasy Of Gold just as it started raining, what an atmosphere! I always get chills and reminded of it when I hear that music now.
Accept's Princess Of The Dawn, a song I really love, which they played for the encore with Balls To The Wall. Both songs got a huge singalong that sounded huge!
Crowd surfing during Megadeth's In My Darkest Hour, which is one of my favourite songs. I couldn't resist, and I stayed up there for ages. It was so metal.
Alter Bridge did a fantastic cover of Deep Purple's Highway Star. I hope they tour here sometime, I would love to see them again.
The Tea Party covering Kashmir and Paint It Black in the middle of Sister Awake which they played last in the set. Brilliant.
I guess that will do, this post is huge! It is late and I am bored...
