Original Soundtracks 1 is a studio album recorded by rock band U2 and Brian Eno under the pseudonym Passengers as a side project. Released on 6 November 1995, the album is a collection of songs written for mostly imaginary films (the exceptions being songs for Ghost in the Shell, Miss Sarajevo, and Beyond the Clouds). Owing to Eno's involvement as a full songwriting partner and the album's experimental nature, the moniker "Passengers" was chosen to distinguish it from U2's conventional albums. It was commercially unnoticed by the band's standards and received generally mixed reviews. Guest musicians on the record included Italian opera singer Luciano Pavarotti (on "Miss Sarajevo") and producer Howie B, who would co-produce U2's following album, Pop (1997). Background According to Eno, near the end of the recording sessions for U2's 1993 album Zooropa, the band hit "a stone wall" and were getting obsessive about small details. At that point, Eno suggested the group do some improvisation, "just turn the tape on and play, so we were working with a broad brush rather than the one-hair brushes we'd been using. It was designed to open us up a little". The resulting recording sessions were productive enough that Eno advocated the band undertake more. After they completed their Zoo TV Tour in December 1993, the band returned to the studio with no particular agenda or project on which to work. Their original intention was to record a soundtrack for Peter Greenaway's 1996 film The Pillow Book. Though the plan did not come to fruition, Eno suggested they continue recording for imaginary films. The result was about 25 hours of recorded experimentation that produced Original Soundtracks 1. At this time, the US charts were dominated by movie soundtrack albums and singles. Once Eno pointed out that it would not be a real ploy for radio airplay, but a spoof of one, U2 agreed to the concept. U2 had frequently improvised in the past, and in the Original Soundtracks 1 sessions they engaged in free-form jamming to video clips from various films. Eno stated, "Listening to the original improvisations as they came off the floor, you feel the excitement of the process ... You have to be careful not to disturb the organic flow of the thing." The group brought in producer Howie B to cut down and mix some of the tracks after several hours of jam sessions had been
