Think Pink: A clickable guide to Kasabian's album

Kasabian's Serge Pizzorno provides an annotated guide to the band's new album, and says he can't wait to prove their critics wrong at Glastonbury.

He's the driving force behind Britain's loudest, maddest rock band - but, in person, Serge Pizzorno is surprisingly serene. Sipping tea from a Kit Kat mug, the guitarist is quietly, if passionately, spoken as he discusses Kasabian's fifth album, 48:13.

"I'm so relieved," he says. "It took me a year. You go through the process of asking, 'Is that chorus big enough? Is that section too fast?'

"So what's amazing is seeing this," he says, indicating a glossy A1 sheet containing proofs for the CD's artwork. "That means it's finished, so I can't do anything else. It's never going to be perfect. I just know that I'm ready to give it away now."

As we discuss the record, Pizzorno grabs a pen and scribbles notes on the fold-out pink booklet - underlining lyrics and circling names in the credits to emphasise his points.

"The whole vision from the start of the record was to keep everything direct," he says. "One-word titles, all the music, the lyrics, everything was direct."

In that spirit, the album is called 48:13, which is precisely how long it lasts.

"I wasn't trying to be clever," Pizzorno says. "The album is the sum of all its parts - and that's 48 minutes and 13 seconds."

Bizarrely, he decided on the title before the album was recorded, having become "attached" to the numbers. "It's so silly," he says, "but for me something about that felt right."

Having to stick to the arbitrary running time helped focus his writing, he says.

"It's weird, because essentially it goes against creativity, but sometimes the idea of being able to do anything hurts your head. Then, if you say, 'Right, this album's not going to have this sort of sound, or this sort of song on it,' then you've got a start.

"Setting yourself restrictions, you can go as mad as you want, as long as it's within the structure."

48:13 is the first Kasabian album Pizzorno has produced on his own. Working in his small studio - "essentially it's just a synthesizer museum" - he was free to indulge his most outlandish ideas.

Kasabian's belligerent, anthemic choruses are still present, but this time they're interspersed with Eastern interludes, Chicago house beats and sudden, unexpected switches.

"In some ways, I've been training 10 years to make this record," he says. "This is the definitive Kasabian record... to date."

As he pieced the record together, Pizzorno was inspired by "the drop" - the climactic build and release of tension employed by dance music. But it was Kanye West's stripped-down and abrasive Yeezus album that really spurred him to action.

"How can you listen to that and not go, 'I need to get in the studio right now?'" he says.

West's album prompted Pizzorno, whose "first instrument was a sampler", to really push the band's hip-hop inclinations.

"They were always there, but now they're leading the charge." To the extent that 48:13 barely resembles a rock album at all.

"God knows what it is," says Pizzorno. "There's guitars on it - but I don't think it's rock. It feels new, that's what it feels like."

The centrepiece is Treat, a seven-minute track that begins as a rambunctious tale of a night out in Leicester ("I'm stood here naked with a junkie sinking Margaritas") before unexpectedly blossoming into an extended, percolating synth groove.

"I felt that song had a really futuristic sound, like future rock," says Pizzorno. "In my head, I was like, 'How do you end a song like that?' And obviously, psychedelic music has been a huge part of my life. And with modern psychedelia, what do you do? You go off into space. That's how you end that song."

Treat has already been successfully road-tested live, much to Pizzorno's delight. "It was a minute into the second part and, all of a sudden, this chaotic gig mosh mentalness just stopped and everyone was just dancing. It was so amazing."

But the track poses a problem for singer Tom Meighan. What on earth does he do during the four-minute instrumental? "Depending on his mood, I think he'll stay on stage and dance," Pizzorno laughs. "But some nights, I just think he'll go off and have a little drink at the back."

In a couple of weeks, "at the back" will be a huge field in Somerset - where the band are, somewhat controversially, headlining Glastonbury.

Their addition to the line-up was received almost as badly as Jay-Z's booking in 2008. Elements of the music press, which still portray Kasabian as beer-throwing "lad rock" Neanderthals, were particularly unimpressed. And Pizzorno can't wait to prove them wrong.

"When we step out on that stage, with all we know and everything we've learned, we have an advantage," he says of the band's blistering live show. "If you're not expecting much, wait until you see what's about to happen to you."

The guitarist sees Glastonbury as "validation" from the industry, but he's even more fired up about another upcoming show.

On 21 June, the band will play to 35,000 people in Victoria Park, mere steps away from where they grew up in Leicester.

"The reason we chose that location is that it's the centre of the town," Pizzorno says. "It's not on the outskirts in a farm, or anything. The train station is two minutes walk, and it sits on the top of a hill where you can pretty much see all of Leicester. It's an unbelievable venue."

The band are excited at the prospect of inspiring a new generation of Leicester musicians, particularly because there were no local role models when they were teenagers.

"The audience will see people from just down the road who created all this from nothing," Pizzorno says. "That's why that gig is so important, for our city to realise that anything is possible.

"It's perfect timing," he adds. "To go on stage and celebrate 10 years of our band, with our best record yet, is great.

"That's going to be our moment, I think."

Kasabian's album, 48:13 is out now. They play Victoria Park on 21 June, and close the Glastonbury Festival the following week.
