At The Gates (Sweden)
The Haunted (Sweden)
Nasum (Sweden)
Refused (Sweden)
Fireside (Sweden)
Cult Of Luna (Sweden)
Dissection (Sweden)
Entombed (Sweden)
Hellacopters (Sweden)

Maybe not your taste but just wanted to point that out anyway. By the way I saw Sigur Ros (Iceland) and Mew (Denmark) last summer at at the Roskilde Festival in Denmark. I love Sigur Ros. They are awesome and even better live. Mew were pretty good too. Kent is from Sweden (same as me) and they suck imo.
