Watch at FMovies. Argentinian cellist Sol Gabetta made her Philharmoniker debut at the 2014 Easter Festival in Baden-Baden with Edward Elgar’s Cello Concerto, the final great work of the composer. The orchestra and conductor also performed the prelude to Wagner’s Lohengrin, György Ligeti’s orchestral piece Atmosphères and Igor Stravinsky’s Le Sacre du Printemps, a work which is entirely focused on the future and pushes the boundaries of classical music in terms of sound, rhythm and energy.
