Folk metal is another unexpected combination that works well, especially considering how popular it currently is. It takes folk instruments, most of which I'm sure you've never heard of, and adds them to the standard metal repertoire. The glory of folk metal is how different each band sounds. Eluveitie uses flutes, bagpipes, and a hurdy-gurdy, while Korpiklaani uses a violin and accordion. I really enjoy songs that start off with a catchy folk beat and switch to a jarring metal riff.
|Not really a conventional metal band.|
Metal is one of the most open and accepting genres of music out there. Many different bands use influences from the weirdest places and make it metal. I didn't even touch on bands that use computers as an instrument, with synthesized beats, drum machines, voice changers, and much more. That's just one of the reasons why metal is the best genre ever.
