Pink Floyd performed the concert version of their famous album "The Wall" only a handful of times, in New York, Los Angeles, London, and Dortmund. This was due to the grandiosity of the performance, which involved constructing a giant wall across the stage between band and audience, not to mention staple Pink Floyd props such as giant screens, flying pigs and pyrotechnics.The performances began with the band in full view, with the giant wall being constructed by roadies out of 420 cardboard bricks throughout the first half of the performance. In the second half, the band would be completely obscured from view behind the wall, but still playing, while extra parts were played in front of the wall by a "surrogate band" composed of Andy Brown on bass, Snowy White on guitar, Willie Wilson on drums and Peter Wood on keyboards. The surrogate band wore masks of the faces of their counterparts in the real band. While playing lead guitar on "Comfortably Numb", guitarist David Gilmour was hoisted hydraulically on to the top of the wall, where he played his famous guitar solo in full view of the crowd. The wall was eventually torn down during "The Trial", and Pink Floyd themselves joined the surrogate band in front of the wreckage of the wall to perform the finale, "Outside The Wall".
