This work of Tangerine Dream is an absolute milestone in the electronic music of the 80's for me. While still dominated the analog Synthys in the 70 you can feel in this album clearly the fresh air, the group received by the digital sound production and also by the new Member J.Schmoelling. Especially after the two previous albums 'Cyclone' and 'force majeure', which act somewhat uninspired, here all the stops are pulled. Unfortunately, this level was no longer achieved on the following CDs!
