Twitter users said Plant's awesome set brought the house down with African-style renditions of the classics "Black Dog" and "Whole Lotta Love."
Between the two was another song, a similarly reworked version of the blues tune "Funny in My Mind (I Believe I'm Fixin' to Die)" Plant included on his 2002 album Dreamland. For this version, the singer pulled out a harmonica and took a solo between verses.
Onstage with Plant for his set was Justin Adams, a member of the Strange Sensation lineup that contributed to Dreamland and its 2005 followup, Mighty ReArranger.
Among the musicians with them onstage was Juldeh Camara, a Gambian instrumentalist and vocalist who released an album called Soul Science with Adams this May.
Camara and Adams have been touring far reaches of the world this year in support of their disc, and in April their headlining set at the WOMAD music festival in Abu Dhabi was boosted by a special guest appearance from Plant.
Singer Beverley Knight wrote on Twitter during the O2 Rockwell show, "Robert Plant is a total legend! My GOD, awesome. Xxxxxx." Afterward, she had her photo taken backstage with Plant, as seen at right. This prompted her to comment, "OMG! Me and the (wolves) legend Robert Plant!!!!"
