Sir Colin Rex Davis was an English conductor, known for his association with the London Symphony Orchestra, having first conducted it in 1959. His repertoire was broad, but among the composers with whom he was particularly associated were Mozart, Berlioz, Elgar, Sibelius, Stravinsky and Tippett.

The London Symphony Orchestra (LSO) is a British symphony orchestra based in London. Founded in 1904, the LSO is the oldest of London's symphony orchestras. The LSO was created by a group of players who left Henry Wood's Queen's Hall Orchestra because of a new rule requiring players to give the orchestra their exclusive services. The LSO itself later introduced a similar rule for its members. From the outset the LSO was organised on co-operative lines, with all players sharing the profits at the end of each season. This practice continued for the orchestra's first four decades.
