Finnish Death Metal is great no doubt, but I disagree with the sentiment that that scene has more quality works than Sweden. Maybe you could make the argument that they have a higher concentration of quality within their own context--but I would argue this is probably because they have less bands to begin with. Also, if we were to simply do a comparison of the quantity of quality releases from either country, I am quite confident that Sweden would trump Finland more than once over.
Edit: Speaking of Finnish Death Metal and Cartilage, I was just looking up some info on them and found the band to be linked with another death metal band called "Wings" who did release a full-length album called Diatribe in 1995. Is it worth checking out (or any of their material for that matter)?
