I do agree with you there. I was just listening to Jon Foreman talking about that. He was very appreciative of the efforts of his prior "labels" but in the end he came back home to his own studio and hired his own producers and others. The album took 2 years -- not for lack of material, quite the opposite, they had far too much, he said. The reason it took so long is they wanted to finally write something that was meaningful to them. They said they loved their prior work that they did with the labels but it felt "a little" compromised. I get the feeling that while they wrote all the songs they wanted to write - the choices of which of those songs wasn't totally in their control. I think they had to haggle over which of their own songs they wrote would be "sold."
They didn't like it, but they didn't gripe during that time either, they just figured if it got great music out to their fans, they would be pleased.
Now however, with Hello Hurricane, the album takes a massive left turn into a strange territory, which isn't exactly uncommon for these guys, but it's all because it's what they chose. The arrangement, the song order of the album, and each song choice.
So getting back to the point, this is one type of interference this particular group had. It's just part of selling with money making machines. If you don't want to compromise, you'll have to fund it yourself.
The irony to this particular story is that they did exactly that. Funded everything, up to the point where another label made them an offer they couldn't refuse. Lowercase people (the banRAB self-label) decided to liscene the rights to Atlantic RecorRAB, but only in so that they could get the music out to the people and to produce any merchandise they like. The rights to the music were retained by the band. Atlantic said "Write whatever you want, we've heard the new album, we know you know exactly what you're doing."
Another interesting thing happened. Since they got the opportunity to write so freely/choose material, they're taking advantage of Atlantic's 360 deal and decided to write 4 albums all at once including Hello Hurricane. They're going to release them one after the other over 6 month time frames probably. That's pretty sick!
