Previn built three separate careers at the top of three different fields: he scored and arranged for MGM starting as a teenager, worked as a celebrated jazz pianist interpreting the Great American Songbook, and became one of the most prominent conductors of his era, leading the London Symphony Orchestra, the Pittsburgh Symphony, the Los Angeles Philharmonic, and the Royal Philharmonic. He won four Academy Awards for film music and ten competitive Grammy Awards spanning all three of his musical lives, plus a Grammy for lifetime achievement.
