The worst one I've seen was Danzig/Superjoint Ritual/Opeth. I got stuck in traffic, so I missed Opeth! So, rather than be out $40 & leave, I figuered I'd stay a while. Superjoint is a shit band & therefore was a shitty show (He shoulda stuck with Pantera) & Danzig was also lame. Not only was the music horrible, but he was barley singing into the mic. I still get mad, just thinking about that night!
