Jari Mäenp&#228#228; - Ensiferum/Wintersun - The stuff he did with Ensiferum was quite good on his own even though I am sure it was mostly what the band wanted rather than what he want. So when he worked on the Wintersun project he really got to show off what he was capable of and did a real good job of it.

Ihsahn (Vegard Sverre Tveitan) - Emperor (Nor), Zyklon-B (Nor), Peccatum, Thou Shalt Suffer, Wongraven, Ildjarn, Embryonic and Samoth (Tomas Thormodsæter Haugen) - Zyklon, ex-Thou Shalt Suffer, ex-Gorgoroth, ex-Satyricon, ex-Zyklon-B (Nor), ex-Arcturus (Nor), Scum (Nor), Embryonic, Xerasia - Even though I don't really listen to Emperor much any more the Legacy they created with In The Nightside Eclipse was truely something to behold. I am not sure who did which parts though I could check out on their videos, the Guitar work was quite differant and played a huge influence on all the Melodic Black Metal bands.

There are many others such as Mikael Åkerfeldt, Arkadius Antonik, and pretty much any Swedish Metal Guitarist but these two imo are my personal favourites.
