Reissue of a private press library recording from the early '70s. 'Soundtrack' was originally produced by Kuckuck in 1973 not for an official and public release, but as a "library" to be used for films, TV and radio. The album is more like an ideal passing bridge between some ritual instances of the previous 'Aum' (1972) and the following successful phase of Deuter during the period when he stays in Bhagwan Shree Rajneesh's ashram in Poona realizing, in parallel to a renewed inner life, masterpieces like 'Celebration', 'Haleakala', 'Ecstasy' and 'Silence Is The Answer'. Musically speaking, 'Soundtrack' presents itself as a heterogeneous work with nocturnal, cinematic, galactic and atmospheric-environmental implications. Electronics remain the predominant factor but can vary from mantra drones or more ceremonial and meditative "space-relax" tones to the most amused formulations of pulsating analog synths that in the hands of Deuter become "toy-equipment" to modulate and explore.
