Dubliners U2 started in their hometown in 1976. They began their legacy rooting their music in the political turmoil that was all around them. Angry, conscious and focused, U2 started a "war with words" which was brough forth by their powerful music. After garnering a large fanbase worldwide as well as critical praise, U2's Bono lead them on a crusade around the world to fight injustices with their music and in interviews.

After having Steve Lillywhite produce their first three "political" albums, U2 looked for a more commercial sound. They hired Daniel Lanois and Brian Eno to produce "The Joshua Tree" and "The Unforgettable Fire" albums which both rocketed them onto the charts all over the world.

After the 80s ended U2 re-invented themselves once again. Incorporating elements of electronics into their rock construct, U2 created a new sound with "Achtung Baby". Bono and the band used their notoriety more than ever expressing their opinions on social matters on a global scale.

Continuing into the 21st century, they are still large and powerful politically while still expressing themselves through their music.
