Actually, J and Jesus and mary chain sounded great (a few overblown solos, but he was younger then).

No I dont think it was really the acoustics that made MBV sound awful. They simply were awful – under rehearsed (if at all) and overpraised by pseudish hacks to the point where they believed their own hype and just made a appalling noise and called it art.
As you may gather, Im not a fan šŸ˜‰
