Bureau B presented a compilation of experimental, electronic music from the GDR's underground cassette scene in 2017 under the title "Magnetband" and now the Hamburg label is following up this thematic focus with the release of two East Berlin artist retrospectives: "Acht Gesänge der schwarzen Hunde" - a compilation of Jörg Thomasius productions from 1980 to 1990 - and "MEZ 31,00" by Dieter Zobel aka Didier Leboz, recorded in 1988 and originally released on Thomasius' Kröten Kassetten label in 1989 - a year of great upheaval in Berlin. Both were members of the legendary avant-garde group Das Freie Orchester. Dieter Zobel's "MEZ 31,00" is one of his many solo releases and also one of his most impressive. Recorded on the Yamaha CX5M, bought with money from his (West German) grandmother's inheritance, the pieces, laid over each other in several loops of the same sequence of varying length, produce a kind of concentrated polyrhythm that sometimes makes one think of ambient music being created in Japan at the same
time.
