Well, here's a brief rundown of some of my favourite ever gigs.
Penthouse. Upstairs at the Island, Ilford, c.1995 or 6. Completely ignored by the indie kids, no more than ten people watching them, I'd never heard of them before and had relatively sedate tastes. Fucking superb, threw themselves around on stage like they were possessed, howling and screaming, thundering bass. Fell in love there and then and Gutter Erotica is still on regular rotation.
Corrosion Of Conformity, Deliverance tour, Camden Underworld 1996. Mate had blagged tickets, I was mostly into indie and grunge and was sneering so much beforehand that my mate told me I could fuck off if I was going to moan about it. Came out in love with riffs again. Wonderful stuff.
Atari Teenage Riot, Highbury Garage, about 1998 or 9. Easily the best gig I've ever been to that didn't involve inflatables.
Flaming Lips, any time I've ever seen them ever.
Mogwai, once I got them.
Radiohead, except the time I saw them at Earls Court. The other three or four times were tear-inducingly brilliant. Everything a great band should be.
