I don’t mean things like 'got some strings in and made a ‘mature’ album, I mean where if you played something from two separate albums you’d swear it was a completely different band. I imagine this is more rare than it might seem, especially if they’ve got a vocalist.
Anyway, who inspired this thread? Mercury Rev. I don’t know their early stuff all that well but whenever I do listen to it, it’s absolutely hilarious how different they sound.
