During the recording of the album, seven CDs worth of material was stolen from the studio, which quickly became available as bootlegs before the release of the album.  The best of the seven discs worth of material was released as a three CD set called Salome.  The other discs were mainly filled with instrumental tracks, and the sound of Larry working on beats.

There was some concern over the cover of the album.  On the back is a picture of Adam Clayton with full frontal nudity.  Due to the concern in some regions, the design team at Works Associates designed an 'X' for placement over Adam's "member" and had it sent to production facilities.  In some cases in the USA a green shamrock was used instead of which the design team was unaware.

Although sounding like nothing that had come before, the album went on to be one of U2's most successful, and launched a very successful two year tour, and five successful singles.
