text: Travels: 1745–1752 In 1745 Gluck accepted an invitation from Lord Middlesex to become house composer at London's King's Theatre, probably travelling to England via Frankfurt and in the company of the violinist Ferdinand Philipp Joseph von Lobkowitz, the son of Phillip Hyacinth. The timing was unfortunate, as the Jacobite Rebellion had caused much panic in London, and for most of the year, the King's Theatre was closed. Six trio sonatas were the immediate fruits of his time. Gluck's two London operas (La caduta de' giganti and Artamene), eventually performed in 1746, borrowed much from his earlier works. Gluck performed works by Galuppi and Lampugnani, who both had worked in London. A more long-term benefit was exposure to the music of Handel – whom he later credited as a great influence on his style – and the naturalistic acting style of David Garrick, an English theatrical reformer. On 25 March, shortly after the production of Artamene, Handel and Gluck together gave a concert in the Haymarket Theatre consisting of works by Gluck and an organ concerto by Handel, played by the composer. On 14 April Gluck played on a glassharmonica in Hickford's Rooms, a concert hall in Brewer Street, Soho. Handel's own experience of Gluck pleased that composer less: Charles Burney reports Handel as saying that "he [Gluck] knows no more of contrapunto, as my cook, Waltz".
