Task: Question Generation
Input (English): Passage: Back in Paris with two years of his grant remaining, Bizet was temporarily secure financially and could ignore for the moment the difficulties that other young composers faced in the city. The two state-subsidised opera houses, the Opéra and the Opéra-Comique, each presented traditional repertoires that tended to stifle and frustrate new homegrown talent; only eight of the 54 Prix de Rome laureates between 1830 and 1860 had had works staged at the Opéra. Although French composers were better represented at the Opéra-Comique, the style and character of productions had remained largely unchanged since the 1830s. A number of smaller theatres catered for operetta, a field in which Offenbach was then paramount, while the Théâtre Italien specialised in second-rate Italian opera. The best prospect for aspirant opera composers was the Théâtre Lyrique company which, despite repeated financial crises, operated intermittently in various premises under its resourceful manager Léon Carvalho. This company had staged the first performances of Gounod's Faust and his Roméo et Juliette, and of a shortened version of Berlioz's Les Troyens.On 13 March 1861, Bizet attended the Paris premiere of Wagner's opera Tannhäuser, a performance greeted by audience riots that were stage-managed by the influential Jockey-Club de Paris. Despite this distraction, Bizet revised his opinions of Wagner's music, which he had previously dismissed as merely eccentric. He now declared Wagner "above and beyond all living composers". Thereafter, accusations of "Wagnerism" were often laid against Bizet, throughout his compositional career.As a pianist, Bizet had showed considerable skill from his earliest years. A contemporary asserted that he could have assured a future on the concert platform, but chose to conceal his talent "as though it were a vice". In May 1861 Bizet gave a rare demonstration of his virtuoso skills when, at a dinner party at which Liszt was present, he astonished everyone by playing on sight, flawlessly, one of the maestro's most difficult pieces. Liszt commented: "I thought there were only two men able to surmount the difficulties ... there are three, and ... the youngest is perhaps the boldest and most brilliant.".
Output (English): What is the name of the person who astonished everyone by playing on sight, flawlessly, one of the maestro's most difficult pieces?
