David Howell Evans was born on 8 August 1961 in East London, England, the second of three children of Welsh parents and he was raised in Dublin, Ireland.

Better known as The Edge or simply, Edge, he formed the band that would become U2 with his classmates at Mount Temple Comprehensive School and his elder brother Dik in 1976.

He is the lead guitarist, keyboardist and backing vocalist for Irish band U2. A guitarist of astonishing versatility, he is known for his low-key playing style, stripped-down guitar riffs with delay effects and reverberation. His minimalistic and textural style has become U2's trademark.

He was rechristened, 'The Edge,' by fellow U2 member Bono Vox (Good Voice). The nickname might have been inspired from Evans’s sharp features, sharp mind or his ability to observe things from the edge without being involved completely.

The Edge is a Protestant Christian. At one point in his career, he wanted to leave the band due to his religious beliefs but later chose not to do so. He has recorded around 14 albums with the band. He was an intelligent student in school and wished to become a doctor or engineer. But after the inception of U2, his commitment to the band and interest in music grew stronger, and he quit his academic ambitions after finishing high school.
