I don't hate the sound of the post-reunion albums, but generally I agree.I can't remember the details, I just recall coming away from the video thinking that he was unhappy with how the record sounded, and that he believes he is more of a perfectionist than the other guys about making sure everything is clean, in tune, and on key.
EDIT: I have to say I agree with him -- I've never particularly liked the muddy, sloppy sound that Caveman typically has given the music, though I think AMOLAD generally sounds better than the others.
Yet I can point to two early '90s albums engineered by Caveman — Rush Counterparts and Billy Squier Tell the Truth — where I absolutely love the sound. They may not be technically precise, but they are clear and the rough edges add to the sound, rather than muddy it. I wonder what changed.
