Here's a video clip posted by a concertgoer who had a balcony seat at Wednesday night's Robert Plant/Alison Krauss/T Bone Burnett concert at the Fabulous Fox Theatre in St. Louis.
Vantage point's nothing to write home about, but the sound is pretty solid and the performance was stellar. Kudos to "WestieMumX3," a.k.a. "Led Zep Gurl," who shot it.
More discussion of the STL show can be found on this Led Zep forum thread.
