In Extremo's technically Mittelaltischer-Metall (Medieval Metal), which is subset of Heavy Metal music that utilizes nominally medieval instruments, although of course supplemented by modern guitar and drum work. At times they're a little overly fond of bagpipes, and I personally don't tend to associate bagpipes with Germans overly much but rather Scots...but then all Mittelaltischer-Metall bands seem to have an infatuation with the bagpipes...Subway to Sally and Tanzwut are examples of that. In Extremo seems to fall somewhere in between NDH bands like Rammstein and more articulate bands like Subway to Sally, and so the lead vocalist has this sort of growly stereotypical German voice that is less aggressive sounding than Rammstein's but still sort of unbelievable as far as anyone really speaking that way. What's most interesting about them though, is that they've done songs in a huge variety of languages, both living and dead, including Gaelic, Spanish, English, Norwegian, Swedish, Icelandic, French, Estonian, Hebrew, Latin, Old High German, and Middle German!
