I don't think they're dying. Have you watched Cuatro (documentary on making of Uno Dos and Tre)? They were totally inspired and motivated while making the albums, you can see on there that they loved it. I think if they were about pleasing fans they would've just rehashed one of their more successful albums instead of making three different sounding albums with a retro rock and roll feel to them and doing something totally new and daunting by playing them to the public for the first time at secret little shows. They were more spontaneous for sure but that's not the same as rushed, I think they had a great time making them and liked the result so they put them out, simple as that. I don't think there's anything to worry about, a bit of a setback with Billie going into rehab and the albums not doing so well but pretty sure they're still as motivated as ever, you can look at the fabulous live shows they've played since then to see that!
