The Black Vial - Noise Frequency PWM
De Stijl Records, 1990.
The Black Vial was a free-form ensemble from Germany, active from the late 1980's to early-mid 1990's. From what is clear, the main-man of The Black Vial was Liebfried Loch, the only member continuously credited through out all releases. Loch himself had been making collages, drones and other pieces since the late 1970's, although The Black Vial was the only major manifestation of his work.
The album borders between drone, outsider folk and general experimental moods and sounds. Despite many conventional instruments being used (guitars, piano, organ) they are used in angular manners as to create long, droning sounds.
De Stijl did release more Black Vial, with 2002's 'The Jaguar And The Yellow Colours.' In 1995, Hidden Records released 'Frozen Morning.' 1990 also saw, along this, a split EP with The Circus Of Doom, released on Swamp Room Records. I am yet to hear any of these releases, although I'd imagine they bare stylistic symmetry with Noise Frequency PWM, due to Loch's pervasive involvement.
Recommended listening for fans of The Sperm, F/i, Ulaan Kohl and the De Stijl catalog.
