Passage:Appearing at the Gasteig in 2005, she performed Chopin's Piano Concerto in E minor with the Münchener Kammerorchester, conducted by Christoph Poppen. In 2008, Babor appeared in a recital at the Ushuaia festival playing works by Beethoven, Prokofieff, Schubert and Ginastera, and Mozart's Piano Concerto in C major, K. 482. In 2009, as part of the project Musik Werkstatt Jugend (youth music workshop), she played Rachmaninoff's Piano Concerto in C minor with the ensemble interculturel in concerts in Munich's Herkulessaal and in Rouen. In 2011, she was the pianist in a concert at the Gasteig concluding a festival to honour the 200th birthday of Franz Liszt on October 22. The program Hommage à Liszt juxtaposed chamber music by Liszt with that by Graham Waterhouse. The music was scored for piano solo up to piano and string quartet, including the premiere of Rhapsodie Macabre.
