Opeth are on the Sounds of the Underground tour. So they're driving down the highway in a big long line of tourbuses, and Opeth are at the front. Lopez is driving, and a deer jumps in the middle of the road. Screaming "ESSE!" he swings the truck around and it rolls over and over. The 20 or so coaches behind them all crash into Opeth and every one of them dies aswell.
So they're all up in heaven, and God is waiting there. He says "since you're deaths were in a huge unexpected disaster, I will allow you to go back down to Earth and finish your Sounds of the Underground tour. I will also grant each band one wish between you."
All of them are amazed at god's kindness, especially Lamb of God, but they don't question it.
First up came Devildriver, and they came to their decision: "We wish we were good musicians." God grants them their wish and they float back down to Earth.
Next came up Poison the Well, who, after hearing Devildriver, changed their minds: "Wow, that's a great idea. We wish to be good musicians aswell."
Up the bands came, one by one, all wishing to be good musicians. Opeth, who were at the back, were conferring. Mendez, Lopez, Lindgren and Akerfeldt walked up to god.
"So, my son," said God. "What will you be wishing for? World peace?"
"No," said Akerfeldt, laughing.
"What, then?" God questioned.
"Make them all bad musicians again."
