In the 1920s the London Symphony Orchestra (LSO) was the city's best-known concert and recording orchestra. Others were the Royal Albert Hall Orchestra, the orchestra of the Royal Philharmonic Society, the BBC's Wireless Symphony Orchestra and Sir Henry Wood's Queen's Hall Orchestra. All except the last of these were essentially "ad hoc" ensembles, with little continuity of personnel, and none approached the excellence of the best continental and American orchestras. This became obvious in 1927 when the Berlin Philharmonic, under Wilhelm Furtwängler, gave two concerts at the Queen's Hall. The chief music critic of "The Times" later commented, "the British public ... was electrified when it heard the disciplined precision of the Berlin Philharmonic ... This apparently was how an orchestra could, and, therefore, ought to sound". After the Berliners, London heard a succession of major foreign orchestras, including the Concertgebouw Orchestra of Amsterdam under Willem Mengelberg and the Philharmonic-Symphony Orchestra of New York under Arturo Toscanini.
