Magnetic songs, this is a difficult disk access that is not familiar with the universe of the first two albums. What one can blame Jean-Michel Jarre, it is ignored in favor of the melodies sound effects and sometimes unpleasant sounds. Some titles are crispants as Part III, which gives the impression of trampling. It seems to me that the tempo is perhaps a bit too high from the beginning so that we have time to get into the music. Other times within the songs save a little rest, with some inspired sound finds, as times of Parts I and IV, but the one in the other, this disc is not quality his two predecessors. Not to be purchased if you are fond.
