I only think of the Wagner opera. Which is not a bad thing. But it does make it super adventurer dragon slayer man, which seems a bit over the top for use in real life.
Wolfram has a very similar feel, but is a little more toned down.
Siegfried Wolfram is totally epic, but I think it's a little too... rocky for real life use. It's awkward to say too, going from -freet to volf-, but probably because I'm not
German. :)
