Electric Light Orchestra (ELO) was a very successful rock music group of the 1970s and 1980s, formed in Birmingham, England. They incorporated the sounds of string ensembles, vocoders and dub echos into rock songs, thereby creating a very sophisticated studio version of rock. The musical content of ELO songs often went far beyond usual chord structures, mixing pop songwriting with classical romanticism and synthesized sounds. The band claim that their music ‘picks up where The Beatles left off.’
