Orango is an unfinished satirical opera by Shostakovich, sketched while he was writing Lady Macbeth of the Mtsensk District. He and his librettists conceived “a political lampoon against the bourgeois press,” concerning a human-ape hybrid. Of the projected Prologue and three acts, only the 40-minute Prologue was completed, in piano vocal score, which was just discovered in 2006. The LA Phil takes great pride in presenting the world premiere of this lost work, newly orchestrated by English composer Gerard McBurney.
