The bulk of the songs that would become The Velvet Underground & Nico were recorded in mid-April, 1966, during a four-day stint at Scepter Studios, a decrepit recording studio in New York City. This recording session was financed by Warhol and Columbia Records' sales executive Norman Dolph, who also acted as an engineer with John Licata. Though exact total cost of the project is unknown, estimates vary from $1500 to $3000

More material from the Gymnasium recordings is finally issued in February 2008 on the bootleg LP Live At The Gymnasium. According to Psychedelic Sounds From The Gymnasium liner notes, the reel-to-reel tape was recorded on the final night - Sunday April 30th 1967.

What we have here is one of the rarest Bowie recordings of all time the Pre Ziggy Stardust Show, only weeks before Bowie had his first meeting (September 10th 1971) with Andy Warhol at the Factory in New York.

Passengers was a group made up of Brian Eno with the four members of U2. It was a one time only project for U2. They had worked with other guest artists on this project and Brian Eno took a much bigger role musically on this release, so it was not released as a U2 project. Because of this, the project got much less notice than it would have under the U2 banner.

The single actually contained two titles on the single for many releases making it a double A-Side with "I've Got You Under My Skin". The track was recorded as a duet by Bono and Frank Sinatra and was released at the same time as Stay. Both were climbing the charts at Christmas of 1993. The duet between Bono and Frank Sinatra was released on Sinatra's Duets album.

Although released in most areas as the first 'traditional' single from Zooropa, Stay was actually the third single released from the album, following Numb and Lemon. Stay would reappear throughout the years on other material released by U2.

Who's Gonna Ride Your Wild Horses was the final single from the Achtung Baby album. The song was reworked extensively from the version found on the album and two versions were released, the full length version and an edit of that remix.

One has become one of U2's most recognizable songs to the public. A hit around the world, the song became one of the songs regularily played on radio in the days following the 9/11 attacks in the US. One is the song that U2 found when they were having difficulty in Berlin moving forward on the recording of the new album. There was talk of whether the band wanted to continue, and after writing and recording this song there was no doubt left that they would.

Mysterious Ways followed the Fly as the second single off of Achtung Baby, released one week after the album itself was released. The Fly had taken the college radio stations by storm, it was so different and although it had success there, it was having trouble gaining airplay on more commercial radio stations. The second single quickly found itself rising in the charts on these stations where the Fly had difficulty.

The Fly was released to radio and video in early September 1991. The rumours had been running hot that U2 was releasing a dance album, that U2 was releasing an album that would be like nothing we'd ever heard from them before. This single didn't disappoint those expecting something different. The album would be more recognizable when it was released, but that was another two months away.

Even Better Than the Real Thing got the full single treatment. A slightly different remix of the album track was released with several b-sides. The single version of the song is most noticibly different at the end of the track, and the drums throughout the song.

Lemon was the second single released from Zooropa. It followed the trend of not being a worldwide release, nor being released in typical formats, that started with the Numb single. A commercial version of this single was not released in Europe. Instead the single only had limited release in the United States, Australia and Japan. Europe and other regions had promotional singles released. The single did chart at number 6 in Australia where the more traditional formats were released.

Released in the Spring of 1995, Melon was the first ever "Fan Club" disc done by U2. It was released with issue #21 of the subscription only magazine, Propaganda. The CD itself was made up of various remixes of tracks released throughout the 90s. Some of these remixes had been released before, where as others such as the Stay (Underdog Mix) were previously unheard. It quickly became a much sought out CD among U2 fans.
