Tramwaj (Krzysztof Kieślowski, 1966) (soundtrack by Skalpel)
What's notable about this early film is that in it one can already perceive themes - loneliness, obessession, voyeurism - that find their way into Kieślowski's later works, especially his remarkable 10-film cycle, Dekalog. He is a fascinating director, whose films deserve to be seen and cherished.
