It was an attempt to showcase their recent remixes and possibly recreate some of the critical success of the earlier remix collection Disco, however Disco 2 is one of the Pet Shop Boys' most poorly received albums by critics and fans. The tracks on the CD were mixed into one long continuous megamix by DJ Danny Rampling. As a result, most of the tracks are in edited versions, having been cut off mid-way through in a crossfade into the following tracks (as a DJ might do while mixing music live). Some of the tracks were reduced by more than half of their original lengths in this way. In addition, some tracks were sped up or slowed down, in order to match the overall tempo of the mix.
Originally, Pet Shop Boys planned to release an expanded version of the 1993 limited album Relentless mixed with their favourite remixes and they got Danny Rampling to try a megamix of Relentless tracks and remixes, but they were not happy with the results.
A limited edition of the album was released in the USA and contained a second CD with rare tracks and remixes.
