If you want a basic distillation of this album's content, I'll provide one to the best of my ability.
I don't know if it's the whole becoming more "spiritual" in prison thing, but Reinkaos is seriously underwhelming. The songs are written in a Soilwork/In Flames type mold and do not really deviate from this pattern. Notvedt, being the gifted guitarist he is, has a good sense of melody and craftsmanship, so even these boring Gothenburg-y songs are far better than most of what is similar. However this does not excuse the perceived laziness of the writing on this album. Each song is unbearably predictable, to the point that if you've heard one, you've heard em all. Really the only distinguishing factor of any of the songs is their tempo, which puts them at a higher variance than your average Discharge clone, but I digress.
Bottom line; like Conservationist once said, this is a smart band dumbing down their music to reach a wider audience. I can't say I particularly blame Mr. Notvedt, as perhaps he had some debts to pay off, but why release this borefest? He just offed himself later that year anyway. Maybe it was just a troll?
