Guitarist and songwriter with U2, The Edge, is 57 on the 8th of August.
Before he became The Edge, Dave Evans responded to an ad placed by Larry Mullen Jnr on a noticeboard at their school in 1976 looking to form a band.
Others to respond include Adam Clayton and Paul Hewson.
Early in the band's career Dave became The Edge and singer Paul became Bono Vox and eventually just Bono.
In 1977 U2 began playing small venues in Dublin and they released their first album Boy in 1980.
The band hit Number One in the UK (9 in Australia and 12 in America) with their third album War.
In 1984 they hit Number One here with the album The Unforgettable Fire and the single Pride cracked the Top 5.
The band's performance at Live Aid in 1985 was one of the event's highlights with Bono inviting female fans on stage during the song Bad.
In 87 the band released their biggest selling album The Joshua Tree containing the hit singles Where The Streets Have No Name, I Still Haven't Found What I'm Looking For and With Or Without You.
Throughout the rest of the 80's the band toured the world and released a documentary film and album Rattle & Hum.
Hit singles, albums and tours continued through the 90's and 2000's.
Actung Baby and Zooropa were great rock albums and the Pop album was pure pop U2 style.
The band has released one great live album, Under Blood Red Sky, and a number of compilations.
The guitar sound and the songwriting by The Edge is an almost irreplacable part of one of the biggest selling bands of all time.
