Achilles Last Stand.

That’s the one.

Robert Plant broke his ankle in a car accident in Rhodes, Greece, in 1975. Led Zeppelin had to cancel a tour and scramble to record Presence while he was in a wheelchair. The album’s urgency and Plant’s physical struggle bled into “Achilles Last Stand” — a seven-minute epic about perseverance and, yeah, taking a stand.

The song wasn’t literally about the crash. Plant has said it’s more of a mythical travelogue. But the circumstances made it. The whole album feels like a band fighting through adversity. “Achilles” is the fight song.

If you want the one track that came directly out of that experience, that’s your answer.
