Written after Mussorgsky had met Russian artist and designer Viktor Hartmann, Pictures at an Exhibition is by far Mussorgsky's most played work. The piece was written when Hartmann gave Mussorgsky two 'pictures.' Hartmann very suddenly died aged 39; following his death, a memorial exhibition was put on in St. Petersburg. Mussorgsky donated the two 'pictures' which Hartmann had given him before he died. Mussorgsky is said to have based the piece on his experiences at this exhibition, which was in memory of Hartmann. The concerto version is performed here by Tamas Ungar in an arrangement by Lawrence Leonard.
