„Europe Train Score” is a thematic audio-visual composition involving the “appropriation” of communication space. The piece has a mobile character. It encompasses the virtual space of a train’s route. The train travels throughout the European continent. The particular fragments of the route – the vectors between the railway stations of major European cities – create a net of miscellaneous connections – the possible railway trips. Those virtual nets of communication connections constitute the basis for the construction of musical structures. The basic elements – the modules from which the composition is constructed - are the audio visual samples of the space of major European railway stations lying along the route of the train. The recordings of film and audio material from the railway stations (Travel Temples) include the sequences/takes of the pedestrian tracks (underground passages, stairs, railway platforms), departures and arrivals of trains, announcements from the loudspeakers, passengers getting on and off the trains, fragments of conversations in different languages, etc. The film and sound material is subsequently subject to studio processing (transformations, sampling, mix, and visual scores). The prepared sequences of film and audio samples are used as visual score structures and independent soundtracks activated during the performance of the piece. The presentation was designed as an audio visual art concert for electronic trumpet, other electroacoustic and electronic instruments, live mix, and multiscreen projections of video samples. The performances of the concerts-shows can take place in all European cultural centres which are situated along the route of the “EUROPE TRAIN SCORE” project.
