Fat White Family are a slap round the face for the comfortable. Their talisman Lias Saudi, militant in his misanthropy, wants change.

“Now all people care about is cocaine and getting a job in city and doing all right,” he protests to The Guide, before his ragtag group of six roll into town for a sold out Concorde 2 show.

For Saudi, lyricist for the London-based scuzz and jangle merchants, the last hopeful youth movement was the riots. The only down side was they weren’t political. “Still,” he adds, “drinking a cup of tea is a political act.”

He doesn’t condone violence but thinks blood on the streets is the only answer to exploitative corporations, yuppification, cracked society.

When Margaret Thatcher died, Saudi’s band unveiled a banner reading “The Bitch Is Dead” over their Brixton HQ, The Queen’s Head. It made The Independent’s front page.

“The day that woman died was one of the greatest days of our lives. We woke up next morning on the front of paper and it was brilliant and everyone was ecstatic.”

The band met in squats in South London and honed their sound in the pub where they lived, drank and worked to pay for both pursuits.

Saudi had dropped out of art school because “it was full of yuppies preparing to become art professionals and pervasively pretentious tutors”.

“Art schools have a negative effect on culture,” he says. “They should all be closed. There should be no such thing as museums. They alienate people from their God given right to create.”

In reaction to the music industry, a “river of extremely middle class West Londoners... incredibly safe, industry sanctioned posh kids playing indie with no blood sweat or guts”, Fat White Family head for the unsavoury side of life.

Every track on debut record Champagne Holocaust carries an explicit warning. Cream Of The Young is written from the point of view of an anarchist paedophile.

“I wanted to make something really horrible you could get off to,” he says, before explaining good music is unsavoury. I can’t think of anything I like that isn’t unsavoury. The Fall is unsavoury. Lou Reed is unsavoury. All the best stuff is unsavoury.”

Fat White Family want to make your skin crawl. Is It Raining In Your Mouth? deals with car-based fellatio. Up tempo sleazy nu wave number Bomb Disneyland – “all your kids are dead kids” – is self explanatory.

“As a society are we really supposed to stand by and accept Mumford & Sons? There is no point even trying.

“The Kasabians and the Arctic Monkeys – like that is the voice of the people, it’s Luddite rock, a terrible hangover from Oasis. It’s the Britpop inheritance, that entire sham of a movement.”

They are fans of Gary Glitter’s output, he reveals.

“He made incredible music. I can’t think of anything that sounds like Rock And Roll Part 2. And whatever anybody does is completely separate to their artistic product.

“Once you make a record it is no longer you. Obviously what the guy has done is deplorable. But it won’t stop me from listening to his music.”

The anger at society is unleashed in the live arena. But Saudi is currently recovering from pneumonia.

“Getting up there and doing it is easy enough. But the problem is you don’t want to go home for a cup of tea after.”
