Interestingly enough, I believe while Kamelot was founded in the US, most of the members are from Europe currently.

One thing I learned ~15 years ago was that Nightwish commissioned lyrics from lyricists (one such commissioned person told me himself I believe a year or two after Dark Passion Play was released - they never used what he wrote for them though) - maybe that helps give the polished impression for some.
