I’m going to organise this by first letter, starting with A:
Alabama 3: I saw these boys at Glastonbury on a scorching June morning. It almost set the scene for a day/weekend of debauchery with their funky rock/country drunken musings finding a happy fit with many fellow revelers. Of course I only knew of them through The Sopranos, but it was a laid back morning set which I could appreciate from a distance, whilst my first (fourth) pear cider of the morning washed down my breakfast.

Ash: Everyone from Northern Ireland has seen Ash live, most of us at least 8 times. It’s not that they’re that good, it’s just that they were all we had. They still perform several hundred shows here each year, but they haven’t had a hit in a long time. I’m doing them misservice- they are still the best band this unholy land have produced in a long time. Anyone who mentions Snow Patrol and their sub Coldplay embarassments will get a slap. Snow Patrol are as worthless as a terrorist. Ash knew how to make a nice pop/punk/rock single and with classics like Goldfinger and Girl From Mars, they always put on a good show, complete with more drunken singalongs.

Acid Mothers Temple: Now we’re talking. I saw these guys in The Pavillion- a Belfast pub/bar/club- the perfect place to witness a bunch of crazy Japanese post-hippies play their wacky jazz/rock/psychadelic fusions and close the night by inserting a guitar into the rafters. A great collection of songs had me dancing groin to groin (face) with the band by myself, whilst the rest of the crowd sat bemused at the farce unravelling before them. Seriously, what did you expect from a band with that name? Releasing a meagre 3 albums every year, you should catch them while you can. And, like me, dance along with a bottle of the cheapest red wine you can find, swooning for 18 minutes of ‘Pink Lady Lemonade’, possibly the greatest song ever (whilst drunk on said wine).

Alice Cooper: I’ve been an Alice Cooper fan since I could first walk. Trash was the first album I ever bought. I quickly grabbed his back catalogue and swallowed every word, and aside from Manic Street Preachers, GNR, and Michael Jackson, no-one else has had such an impact on my own songwriting. I never thought I would ever get to see him, but this year, finally, I got the chance. He was only a support act to a band who will remain unnamed until I get to that letter, but he blew everyone else off the stage with a mini show. Everyone shold have Killer and Hey Stoopid in their collection, showing the two most prominent sides of the man’s oevre- the early progressive blues style, and the later metal leanings.
