Declan Patrick MacManus OBE, known professionally as Elvis Costello, is an English singer, songwriter, record producer, author and television host. According to Rolling Stone, Costello "reinvigorated the literate, lyrical traditions of Bob Dylan and Van Morrison with the raw energy and sass that were principal ethics of punk", noting the "construction of his songs, which set densely layered wordplay in an ever-expanding repertoire of styles." His first album, My Aim Is True (1977), is widely regarded as one of the best debuts in popular music history. It spawned no hit singles, but contains some of Costello's best-known songs, including the ballad "Alison". Costello's next two albums, This Year's Model (1978) and Armed Forces (1979), recorded with his backing band the Attractions, helped define the new wave genre. From late 1977 until early 1980, each of the eight singles he released reached the UK Top 30. His biggest hit single, "Oliver's Army" (1979), sold more than 500,000 copies in Britain. He has had more modest commercial success in the US, but has earned much critical praise. From 1977 until the early 2000s, Costello's albums regularly ranked high on the Village Voice Pazz & Jop critics' poll, with This Year's Model and Imperial Bedroom (1982) voted the best album of their respective years. His biggest US hit single, "Veronica" (1989), reached number 19 on the Billboard Hot 100.

Elvis Costello was born Declan Patrick MacManus, on 25 August 1954, at St Mary's Hospital in Paddington, West London, the only child of a record shop worker and a jazz musician. Both parents were from the Liverpool area and had moved to London together a few years earlier. Costello's father was Catholic and of Irish descent, but his mother is neither.
