As a courtesy to their fan club, U2 began releasing a series of exclusive albums in the mid-‘90s. This rarities album was issued in 2009 to subscribing members of U2.com, and it contains two discs of unreleased tracks, B-sides, alternate takes, and cover songs. Although most of these tunes can be found elsewhere -- many were released as bonus tracks on the remastered versions of Boy, October, War, and The Joshua Tree -- it’s helpful to have them all in one place, especially since they occasionally trump the material that did appear on U2's official albums. Of particular note are the discarded songs from the recording sessions for All That You Can’t Leave Behind and How to Dismantle an Atomic Bomb, including “Native Son” (a primitive -- although arguably superior -- version of “Vertigo”), "Fast Cars" (which includes the lyric that gave How to Dismantle an Atomic Bomb its name), and the charming, semi-psychedelic “Flower Child.”
