Weekend Rock Question: What Is the Best Live Album in Rock History?

This month, Led Zeppelin are finally releasing a live album of their 2007 reunion concert at London’s 02 Arena. They may be one of the greatest live acts in rock history, but the only live album they released during their original run was the soundtrack to The Song Remains the Same. They’ve since released How the West Was Won, which drew from two California shows in 1972, but a ridiculous amount of great live content still sits in the vault.
Most great live bands were more generous with their tapes. The Who gave their fans Live at Leeds, James Brown put out Live at the Apollo and the Allman Brothers released At Fillmore East. The list goes on and on.
Now we have a question for you: What is your single favorite live album of all time? It has to be something officially released by the band. No bootlegs. Please only vote once, and only for a single album.
