Led Zeppelin: The Conspiracy Of Silence, Live at Sports Arena, San Diego, March 14, 1975.

For decades after the breakup of Led Zeppelin, fans were led to believe there was nothing left in the vaults worthy of release. Then in early 2004, an amazing recording emerged in Japan of a fantastic quality Led Zeppelin show from 1975, almost 30 years to the day. It was not a TV show. It was not a live concert broadcast on radio. This was a brand new soundboard recording. The conspiracy of silence had been broken....

...The initial reaction after the euphoria of its discovery was that the San Diego show had its faults. Robert Plant was tired and his voice was mangled and sore. The band too struggled with John Paul Jones and Jimmy Page missing cues. Only drummer John Bonham was in high spirits. You can hear his onstage banter during the marathon Moby Dick. Since then other better shows of soundboard quality have escaped from the vaults
