Against Agamemnon Lyrics
bright red all along the thin canvas wall
i stepped outside, for a little air
i stepped outside to get away from it all
i went out to the front, and saw the purple sky
making jokes about my condition
i'll be back in half an hour
watch over the children
i'll be back in half an hour
hey hey la la la
hey hey la la la






i don't think he'll be back in a half an hour.

Heh, shewouldnt, funny.
For anyone wondering, this song is based on the ancient Greek tragedy "Ajax". Ajax was one of the Greek heroes during the legendary Trojan War. Most of the real action happens before the play (the Greek audience would have been familiar with the background): Ajax is angry with Agamemnon, the Greek leader, because he favored Odysseus over Ajax in a contest. Ajax plans to kill Odysseus and Agamemnon, but the goddess Athena, who has a special affection for Odysseus, drives Ajax temporarily mad; Ajax thinks that a herd of pigs are Ajax and Odysseus and their man, and drives them into his tent to kill them.
As the play opens, Ajax is inside his tent, killing the pigs ("red red, red everywhere/ bright red all along the thin canvas wall"). Odysseus is outside; Athena makes fun of Ajax in his madness ("saw the purple sky/ making jokes about my condition") and invites Odysseus to do the same; he demurs, noting that the same could happen to him.
When Ajax comes to his senses, he is humiliated by what has happened to him, has a little talk with his wife, and wanders off to kill himself.

Even before I knew the backstory (thanks jfruh), I still thought it was about suicide. I pictured a guy imagining blowing his brains out, getting blood on the walls, and being so upset by this image he walks out of the house to clear his head. Instead, he sees the sky in the same color of red, "mocking" him. He can't get away from the thoughts, so he finally decides to end it all.
