Check this bootleg 1971 Led Zep audio from Japan

A new Led Zeppelin box set is on the way, which could mean another lawsuit. That's because it's a bootleg from Japanese bootleg label Empress Valley. The limited-edition 12-CD set of their 1972 Japanese tour will feature upgrades to the audio quality. 

Empress Valley recently released soundboard recordings from Zeppelin’s 1971 Japanese tour.
