Pictures at an Exhibition is an album by British progressive rock band Emerson, Lake & Palmer, released in 1971 as a live album and re-released in 2001 as a remastered edition including both live and studio versions of Modest Mussorgsky's classical piece Pictures at an Exhibition. The original live album was recorded at Newcastle City Hall in North East England. The opening track of the album was played on a Harrison & Harrison pipe organ which was installed in the City Hall in 1928. The organ console is some way above stage level, at the top of a stepped terrace used for choral performances. The drum roll connecting the opening track to the next served to cover Emerson's dash back down to the stage.
There was also a video made of a different live performance (Lyceum Theatre, 9 December 1970). This had a limited theatrical release in 1973, and a remastered DVD release with Dolby surround sound in 2000. Being a live album, sometimes Keith Emerson's voltage-controlled Moog oscillators went out of tune, due to humidity and temperature.
