David Howell Evans, better known as the Edge or simply Edge, is an English-born Irish musician, singer, and songwriter. He is best known as the lead guitarist, keyboardist, and backing vocalist of the rock band U2. A member of the group since its inception, he has recorded 14 studio albums with them as well as one solo record. His understated style of guitar playing, a signature of U2's music, is distinguished by chiming timbres, use of rhythmic delay, drone notes, harmonics, and an extensive use of effects units. Born in England to Welsh parents and raised in Ireland, the Edge formed the band that would become U2 with his classmates at Mount Temple Comprehensive School and his elder brother Dik in 1976. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most successful acts in popular music, with albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, the Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, the Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally served as co-lyricist. The Edge met his second wife Morleigh Steinberg through her collaborations with the band. As a member of U2 and as an individual, the Edge has campaigned for human rights and philanthropic causes. He co-founded Music Rising, a charity to support musicians affected by Hurricane Katrina. He has collaborated with U2 bandmate Bono on several projects, including songs for Roy Orbison, Tina Turner, and Martin Garrix, and the soundtracks to the musical Spider-Man: Turn Off the Dark and the Royal Shakespeare Company's London stage adaptation of A Clockwork Orange. As a member of U2, the Edge has won 22 Grammy Awards and has been inducted into the Rock and Roll Hall of Fame. Several music publications have ranked the Edge among the greatest guitarists of all time.
