Argentinian cellist Sol Gabetta made her Philharmoniker debut at the 2014 Easter Festival in Baden-Baden with Edward Elgarâs Cello Concerto, the final great work of the composer. The orchestra and conductor also performed the prelude to Wagnerâs Lohengrin, György Ligetiâs orchestral piece AtmosphĂšres and Igor Stravinskyâs 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.
