Fejd is a band hailing from Sweden, and the music they play can probably best be characterized as folk or world music. As far as I know, they only have one or two albums out, and I've only listened to one of them thus far. All of their music incorporates bagpipes, violins, and other traditional instruments, so you won't hear anything electric; also, all of their music is sung only in Swedish, which to me is as it should be.
