"When I was writing the record I was listening to those bands. I mean, I was working with one of them [Wilson co-produced and performed on Opeth's Deliveranceand Blackwater Parkalbums; he was also asked to produce Katatonia's upcoming album]. And it was a pleasure to be working with them, just the sophistication of the music."
It seems Steven Wilson was just asked to produce the album. The wording was pretty confusing. The new Katatonia was produced by the band I think.
