Question: Who founded the famous chain of music-themed restaurants which opened its first establishment in the city Chopin went to in the spring of 1848?

This tour was suggested to him by his Scottish pupil Jane Stirling and her elder sister. Stirling also made all the logistical arrangements and provided much of the necessary funding. In April, during the Revolution of 1848 in Paris, he left for London, where he performed at several concerts and at numerous receptions in great houses. <SEP> possibly the first venture into fictional treatments of chopin's life was a fanciful operatic version of some of its events. chopin was written by giacomo orefice and produced in milan in 1901. all the music is derived from that of chopin. <SEP> On June 14, 1971 he and Peter Morton started the first Hard Rock Café (HRC) restaurant in London's fashionable Mayfair district. The restaurant combined rock music, memorabilia related to rock 'n' roll and American cuisine. <SEP> at the end of 1831, chopin received the first major endorsement from an outstanding contemporary when robert schumann, reviewing the op. 2 variations in the allgemeine musikalische zeitung (his first published article on music), declared: "hats off, gentlemen! a genius." on 26 february 1832 chopin gave a debut paris concert at the salle pleyel which drew universal admiration. the critic françois-joseph fétis wrote in the revue et gazette musicale: "here is a young man who ... taking no model, has found, if not a complete renewal of piano music, ... an abundance of original ideas of a kind to be found nowhere else ..." after this concert, chopin realized that his essentially intimate keyboard technique was not optimal for large concert spaces. later that year he was introduced to the wealthy rothschild banking family, whose patronage also opened doors for him to other private salons (social gatherings of the aristocracy and artistic and literary elite). by the end of 1832 chopin had established himself among the parisian musical elite, and had earned the respect of his peers such as hiller, liszt, and berlioz. he no longer depended financially upon his father, and in the winter of 1832 he began earning a handsome income from publishing his works and teaching piano to affluent students from all over europe. this freed him from the strains of public concert-giving, which he disliked. <SEP> London has numerous venues for rock and pop concerts, including the world's busiest arena the o2 arena and other large arenas such as Earls Court, Wembley Arena, as well as many mid-sized venues, such as Brixton Academy, the Hammersmith Apollo and the Shepherd's Bush Empire. Several music festivals, including the Wireless Festival, South West Four, Lovebox, and Hyde Park's British Summer Time are all held in London. The city is home to the first and original Hard Rock Cafe and the Abbey Road Studios where The Beatles recorded many of their hits. In the 1960s, 1970s and 1980s, musicians and groups like Elton John, Pink Floyd, David Bowie, Queen, The Kinks, The Rolling Stones, The Who, Eric Clapton, Led Zeppelin, The Small Faces, Iron Maiden, Fleetwood Mac, Elvis Costello, Cat Stevens, The Police, The Cure, Madness, The Jam, Dusty Springfield, Phil Collins, Rod Stewart and Sade, derived their sound from the streets and rhythms vibrating through London.
