The unfinished satirical opera, "Orango" whose Prologue was sketched in 1932 by Dmitri Shostakovich with a libretto by Aleksey Nikolayevich Tolstoy and Alexander Osipovich Starchakov was later abandoned and discarded. The manuscript was found by Olga Digonskaya, a Russian musicologist, in the Glinka Museum, Moscow in 2004 and orchestrated by Gerard McBurney; this work was premiered on 2 December 2011 in Los Angeles, California by the Los Angeles Philharmonic under Esa-Pekka Salonen (conductor) and staged by Peter Sellars (director).
