Ah yes, an easy one for me
Top of the list for me would have to be BLAZE in Plymouth. Fucking unbelievable, man. The songs are, of course, amazing, and the band played top form that night. The man of the night was easily Blaze Bayley himself, though. He is an incredible frontman. He introduced practically every song, made some tremendous speeches, and had the crowd involved in something for practically all the time he wasn't singing. They played Born As A Stranger for their last song, and I lost a shoe in the mosh. I threw it onstage so not to loose it forever, and John Slater promptly picked it up and put it on the neck of his guitar!
afterwards I got my limited edition copy of Tenth Dimension signed by the band. Probably one of the best nights of my life
The other highs were:
Deep Purple - Plymouth Pavillions. It was a seated gig, and they opened with Fireball which is naturally a song you can't sit down to. A guy ran to the front and started headbanging, promptly got dragged away by security and got cheered by the front few rows. During the solo Ian Gillan jumped offstage to bollock one of the guards, and had a bit of a talk to us after the song about "what happened to rock'n'roll?". Truly fantastic! 'bout halfway through the set half the front section left their seats anyway. Fucking brilliant night.
Iron Maiden - Brixton Academy. What can I say, really?
Seqouyah - Plymouth. Bloody pity they split up now
