Zero degrees on the Kelvin scale is absolute zero, the lowermost limit of the temperature scale. According to Nernst's heat theorem, the absolute zero of 273,15°C = 0 Kelvin is fundamentally unattainable. Kelvin, the hero of Andrei Tarkovsky's science fiction film Solaris, has once more set off, this time not to liquidate the space station »Solaris«, but for the former GDR broadcasting centre on Nalepastraße in Berlin. As in Solaris, a mysterious disorder in the broadcasting centre leads to a process of dissolution, whose force materialises desires, memories and traumata as »guests«. In a double projection, Kelvin's subjective eye glides slowly through the empty rooms. What is seen and what is imagined unfold in parallel fashion, the past in the present. If the future hasn't become what it was once meant to be, does that then mean, arguing to the contrary, that in the future, the past can be corrected at will? Both showplaces, the space station Solaris and the GRD broadcasting centre on Nalepastraße, testify to a failed utopia. TME – Tokyo Metropolitan Expressway 1970/2005 »For their 10-part video installation Radio Solaris / 273,15°C = 0 Kelvin at the Yamaguchi Center for Arts and Media, Japan, Fischer and el Sani produced a new section in Tokyo – a double projection with two trips on the expressway. One projection shows an original scene from Tarkovsky's Solaris (1970), a ride on the TME; the other a remake of this scene, shot in 2005. Both sequences are much the same, only the brief moments outside the tunnel give the idea that time has passed, because there are more, and bigger, high-rise buildings.« Robert Lippok on the music: The significant thing about the levels of sound in Tarkovsky's films is often the way noises and music are interwoven. On one hand, the noises that – sometimes through exaggeration, sometimes through alienation – make conventional film music completely superfluous. On the other, the music, often generated electronically, whose strangeness creates what he calls an »ersatz reality«. In Solaris these two elements mix in an ingenious way and generate an intense atmosphere that goes far beyond mere illustration of the pictures.
