The organ is on all fronts in this programme, which the Orchestre national de Lyon will play again two days later at the Philharmonie de Paris: with the orchestra in Bach’s monumental Passacaglia and Fugue which Respighi orchestrated for Arturo Toscanini, and in Strauss’s famous Thus Spake Zarathustra, whose cosmic chords will forever be linked to Stanley Kubrick’s film 2001, Space Odyssey ; in solo, in Ligeti’s Volumina (1962), a piece which reinvents organ music through the very essence of sound and which opens into a world of unreal and extraordinary forms and colours; lastly as soloist, with the orchestra, in Copland’s Symphony. This is in fact a concerto, where the organ unfurls a gigantic palette: soaring tonalities in the prelude, bluesy and jazzy in the wild scherzo, triumphant Finale. Profoundly American, it is one of Copland’s most accomplished works. At the time of writing it (24 years old) he was fascinated by Stravinsky and Prokofiev. This concert marks a reunion between Vincent Warnier, the ONL and Leonard Slatkin, a trio which shares a deep complicity.
