The Hard Rock based solo project from Austrian singer/guitarist Topas involved a plethora of guest musicians, involving a good number of former WOLFGANG AMBROS members (guitarist Johan Duansen, keyboardist Christian Kolonowits and drummers Harmut Pfannmüller and Jürgen Zöller (also a former member of WOLF MAAHN).

Contributions also came from guitarists Richard Kersten and Nick Paine, bassist Reinhard Besser, drummer Brat Howell and keyboard players Dieter Kolb and ex ENIGMA man Michael Cretu. Incidentally, Pfanmüller, Kolonovitts and Daansen had all played together in EINSTEIN previously, whilst Pfanmüller and Daansen were later involved with ex-RAINBOW keyboard player TONY CAREY's PLANET P PROJECT in 1983.
