Declan Patrick MacManus OBE (born 25 August 1954), known professionally as Elvis Costello, is an English singer, songwriter, record producer, author and television presenter. Per 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."
