Isn't it funny how the typical progression always seems to be a move toward radio-friendliness and not away?
I think it's perfectly normal for a good band. A lot of people think/complain that this means the band "sold out". Honestly, I don't think there are many bands that start out with the premise that they want to always appeal to smaller and smaller audiences. Most bands want people to like their music (and they want to eat, and live in a place with heat - stuff like that). Over time, if they're good, the band gets better at writing catchy songs, more people "find" them, and...they become more popular - some of that is the band's doing, some of it is the audience's. I don't see a single thing wrong with that.
If you start any other kind of business, and it succeeds, it's success. In music, for some folks, I think they're just complaining that now they have to pay more money for tickets, and sit further from the band in a larger venue - they liked it better when they were one of very few fans of the band. The band didn't "sell out", your taste in music just got "justified" by lots of other people agreeing with you. If you want to be a fan of an up and coming band that hasn't become popular yet, there are scads of then, and there's never been a better time to find new bands.
If you're a musician, and you don't want to be bothered by large audiences, there is a solution. Play jazz. Preferably modern jazz. That'll do it.
