The series began in 2009 with a plan to release all the music from The Ultimate Edition in chronological order.
[1][2] One noticeable difference between the original box sets and the La Vie Electronique reissues is the indexing of the discs themselves.
While the individual movements of longer pieces were indicated in the sleeve notes of the box sets, those compositions were presented as one continuous track.
The latter two selections were also not repeated in The Ultimate Edition set, though both are in fact variations of "Ballet pour Le Docteur Faustus".
Similarly, "Discover Trakl" is an extended version of the track "George Trakl" from the 1978 album X, and this longer version (in a slightly edited form) was included in place of the original on that album's 2005 reissue.
