Right before TD entered the stage during their Europe gigs in 1997, spectators could hear some mellow music, mostly consisting of re-arranged well-known TD material overlayed by some nature, animal or environment sounds. "On public demand", as stated in the booklet, this "pre-concert ambient music" has become available on the CD Ambient Monkeys on the TDI label. Pre-release CDs had been sold on the merchandise stall during TD's British tour in November 1997 first. The tracks of this version were not indexed. The official CD came without the track Largo (from Xerxes) and was released with different cover artwork in June 1998 in the Dream Dice box set, and later also separately. In 1999 Ambient Monkeys was re-released once more with different cover design.
In March 2009 the album was re-released with completely different cover design as part of an extensive digipack series (consisting of a total of more than 60 CD and DVD releases) by the Germany based Membran record label.
