Letter to Peter, on Saint François d'Assise by Olivier Messiaen
Plot: In 1992, Olivier Messiaen's epic opera "Saint François d'Assise" was brought to the Salzburg Festival in a staging by Peter Sellars. The distinct visual appearance that Sellars lent to the opera, where video monitors with powerful images are used as a sort of high-tech metaphor for a cathedral's stained glass, drew critical acclaim and is still talked about as a watershed moment in opera to this day
