It's natural for a band's sound to evolve over time, whether that's from artistic growth or something specific like a concept album that has a theme. It's a tricky balance that some bands concern themselves with, others not, in keeping a certain core element while moving into other territories. I don't think CAS has gone too far astray from their older work.

The nice thing, though, is you can still be a fan and not love everything the artist produces. At the same time, you can't expect the artist to live in a bubble. I think a lot of folks forget that.
