Robert Plant made a guest appearance Tuesday at London's Royal Albert Hall during a concert by violinist Nigel Kennedy.
Plant performed Led Zeppelin's "Kashmir" as well as a cover of "Hey Joe."
The show was billed as Nigel Kennedy and Friends, according to Rolling Stone.
Led Zeppelin fan site LedZepNews.com captured audio of the performance and posted it Thursday morning.
The rendition begins starkly with just Plant's vocals and some light instrumentation. The full band comes in with a crash by the second verse and the song takes off from there.
