They usually also have the problem, that their fans often don't like them to change. They want more of what they know, but better. Not different (especially in entrenched genres).
Turisas for example, a band making songs mainly about vikings. I watched them live a few years ago - was quite good, but the band made remarks that they do not take the whole viking thing that serious (nostalgic buisness they called it) and would rather play something else. And they did one song in the end, in a quite different style (sounded like futuristic metal) but the audience was not thrilled - they were there for viking and glorious battle metal. So this is what Turisas are still playing, this is what brings them money, but they have not made a new album in over 10 years, but how can you make a good album, with a theme you don't find that exiting anymore?
