I was at Rock am Ring when it was QOTSA, Tool, Radiohead, Manic Street Preachers, Orbital, and Outkast... and then Tool played on the second stage at the same time as Radiohead, and people were throwing beer bottles at the band and demanding they hurry up and play Creep already. Guess I should have gone and seen Tool instead.
It was a lame festival... as I walked into the crowd, some guy wearing a beer helmet was being hauled out at noon on a stretcher, and when I got in the crowd some guy whipped his dick out and started pissing all over the crowd around him, laughing drunkenly while apologizing while he pissed on my shoes (and the shoes of everyone around me).
It sucked!
My German friends warned me not to go.
