***A collection of works created at Polish Radio Experimental Studio by pioneer of minimalism Tomasz Sikorski and by his friends and followers. Four by Sikorski: Echoes II (1963); Antiphones (1963); Diario 87 (1987); Solitude of Sounds (1975). Two by Száblocs Esztényi: Created Music No 3: in memoriam Tomasz Sikorski (1989); Concerto (1971). One by Kasia Głowicka: Presence (2007). As opposed to American minimalism (with its urban soundscape flavor that emerges from frenetic human interaction), or Dutch minimalism (informed by a culture of activism), the Polish variation has been called “mystic minimalism” because of the personal experiences and environment of its creators, and their interest in expressing emotions in a grandiose way. Philosopher-minimalist Sikorski was concerned with the meditative properties of his compositions (which seem to long for brutal beauty), and impressed by the existential crisis in Kierkegaard’s The Sickness Unto Death. His attraction to despair may have had roots in personal tragedy, where intoxication, abandonment and ridicule plagued his existence. Twenty-four-page booklet.
