"Songs Of Innocence" is U2's most personal work: It includes seventies rock with the first influences of the band, featured beyond punk rock of the early eighties, but also ambient music. It also provides information about how and why the band originally came together. The first single "The Miracle (Of Joey Ramone)" deals with the Ramones frontman Joey Ramone, who died in 2001. Bono and Joey admired not only the music of the other, but were also good friends.
The album revolves around the home of the band and their families, but also about relationships and discoveries. It was recorded in Dublin, London, New York and Los Angeles, after it was produced by Danger Mouse, Paul Epworth, OneRepublic's Ryan Tedder, Declan Gaffney and Flood.
In addition to the 11 tracks on the standard CD, the Deluxe contains a total of 21 songs, including the acoustic versions of selected album tracks and four bonus tracks. The double vinyl includes 11 tracks of standard and one bonus track.
