Augustyn Bloch was a Polish Organist & Composer largely known in these circles for his extended tenure chairing the "Warszawska Jesień," or "Warsaw Autumn" International Festival of Contemporary Music - you've likely come across one of the myriad "Yearly" Polskie Nagrania Muza compilations bearing the names of the Polish late 20th Century Avant Garde's elite - Włodzimierz Kotoński, Bohdan Mazurek, Andrzej Dobrowolski, Zygmunt Krauze, Bogusław Schaeffer, etc.

Working comfortably across different disciplines - his Violin Concerto, famously recorded by Yehudi Menuhin in 1964, is a wonder of Bartok-ian form - Bloch undoubtedly felt the pull of Electronic Music's octopus-like tendrils & by the late-late 70s he was exploring the intersection of tape-sound & his own tone-wheel exploits, yielding an amazingly unique strain of music.

In that great Library Music tradition of casting proper, academic Avant-Garde composition as "Mood Music" fodder - presumably for license in Science Documentaries, Horror & Sci-Fi films, etc. - in 1980 Gerhard Narholz commissioned a pair of titles for his fledgeling Sonoton Production house, with "Unusual Sounds Vol. 1 - Reflections" being only the imprint's second title - after Mladen Franko's "Amazing Space" - followed by "Unusual Sounds Vol. 2 - The Brain," 31 catalogue numbers later, albeit still in the same year (!?)

This Creel Pone replication features both titles etched onto two separate discs & housed in a single outer sleeve with a reproduction of each LP's jacket, reproducing the incredible apropos metal-drop morphisms of the cover art in fine form.
