But if they do get back together, he has no interest in bringing in a near-complete album like he used to. Wilson tells Under The Radar: "I would have to say to the guys, 'Look, there's no point in me writing the material. If I were to do that I might as well do it for a solo record. Let's try writing together, or writing in partnerships."

He accepts that, no matter how successful his solo career becomes, he'll always be asked about Porcupine Tree. "I think of someone like Peter Gabriel - people are still asking him when Genesis are getting back together," says Wilson.

"It's not a bad thing; it's a flattering thing. When you step out of a reasonably successful band it doesn't matter how good your solo work is. People always have a nostalgic attachment to the band identity. I'm used to it now.
