The Electric Light Orchestra (ELO) was an English rock band formed in Birmingham in 1970 by songwriters and multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan. Their music is characterized by a fusion of pop and classical arrangements with futuristic iconography. After Wood's departure in 1972, Lynne became the band's sole leader, arranging and producing every album while writing nearly all of their original material. From this point until their first break-up in 1986, Lynne, Bevan, and keyboardist Richard Tandy were the group's only consistent members.

ELO was formed out of Lynne's and Wood's desire to create modern rock and pop songs with classical overtones. It derived as an offshoot of Wood's previous band, the Move, of which Lynne and Bevan were also members. During the 1970s and 1980s, ELO released a string of top 10 albums and singles, including the band's most commercially successful album, the double album Out of the Blue (1977). Two ELO albums reached the top of the British charts: the disco-inspired Discovery (1979) and the science-fiction-themed concept album Time (1981).

ELO's music is characterized by its use of orchestral arrangements, synthesizers, and Jeff Lynne's distinctive songwriting and vocals. The band's lyrics often deal with themes of love, loss, hope, and science fiction. ELO has been cited as an influence on a wide range of artists, including Coldplay, Radiohead, and Oasis. In 2012, ELO was inducted into the Rock and Roll Hall of Fame.
