I'm going through the same kind of issue here. To be honest tho, I think that if my fans appreciate my work, they even appreciate its natural evolution. Like, I've been doing mostly, disco, funk and stuff for years and just now I'm going through paths of experimentation. In my opinion, if they love my work they'll love the direction I'm taking. If they don't, I'm still happy I'm trying something new. It may sound a little selfish maybe, but that's how I always worked :3
