Kaizers Orchestra:
Huh, something weird happened with the embedding, you'll have to youtube it yourself.
and Týr:
It also happened here, surprise surprise
Both awesome scandinavian bands although very different.
Kaizers Orchestra is a strange mix of contemporary pop and alternative with a bit of folk thrown in.
I've seen them live 4 times, they're quite brilliant on-stage, playing on oil drums, wearing gas masks and not afraid to involve their audiences. One concert they invited a young guy up on stage because it was his first concert and baptised him, which everyone including him thought was awesome.
Týr is actually also folk-inspired, although they're more metal/hard rock with texts focusing on the norse mythology. Their lyrics are usually in english, except when they without warning switch over to their native language, Faeroese, which is coincidentially also the language most closely related to the old norse language.
