The most extraordinary virtuoso in musical history must surely be Franz Liszt. This documentary, featuring many leading Liszt experts (including Charles Rosen, Leslie Howard, Antonio Pappano and Evgeny Kissin), concentrates on his earlier years when he was travelling across Europe almost non-stop, fuelling the phenomenon described by Heine as "Lisztomania." It was also the time of elopement with Marie, Comtesse d'Agoult, in a move that scandalized polite society as much for its unorthodox nature as for its moral dubiety. These were the years of artistic journeying to which Liszt would one day return in the evocative musical colors of his Annees de pelerinage.
