From Discogs.com : "Asmus Tietchens is a German electronic musician who has pursued "absolute music" through an almost mathematical process of rigid formal exercises. With strong ties to Karlheinz Stockhausen's early electronic work, Tietchens specializes in irregular patterns of sonic abstractions that are suspended in gray drones to create cold textural voids from external references. His music is often inspired by and refers to the texts of the philosopher Emil Cioran.
PBK has been working in the areas of noise, ambient and electroacoustic music since 1986. PBK is an acronym for Phillip B. Klingler, born in 1960 in Flint, Michigan. In the early 80's Klingler studied art at Northern Michigan University and CSU San Bernardino. He exhibited his expressionistic paintings in the Los Angeles area and was active on the international mail-art scene."
"Five Manifestoes" was released by Realization Recordings in 1992.
