LP version. Bureau B present a reissue of Tyndall's Durch Die Zeiten, originally released in 1983. Having successfully released three albums, the Berlin-based electronic duo Tyndall fell out so badly with one another in 1983 that they ended up splitting the fourth album in two, taking a side each. Jürgen Krehan's half showcases his customarily nimble synth-pop, as well as several pieces influenced by classical music. Rudi Langer launches into celestial revelry on the other side, underpinned here and there by a driving beat. Nevertheless: both sides sound unmistakably like Tyndall. On Durch Die Zeiten Jürgen Krehan used a music computer for the first time, aided by a mysterious musician by the name of Yin Yang from Tokyo, according to the original credits, who apparently contributed computer programs and two tracks entitled "Barock" and "Klassik". Yin Yang may well be a pseudonym Krehan used, also surfacing on the rare and highly-prized cassette Flusswelt released on David Elliott's YHR Tapes label in 1983. As anticipated by the last tracks of the previous album, 1982's Reflexionen (BB 288CD/LP), the pieces here are structurally clearer, more developed, moving in a more classical direction, away from synth-pop. Rudolf Langer opens the B side with a track called "Kambrium". This geological era was ushered in by the "Cambrian explosion". He paints this "big bang" of animal life in almost religious, idyllic, fanciful tones, with roaring sounds and futuristic pitch sweeps. The next track, "Silur", references the Silurian period, characterized by massive tectonic activity which precipitated biological crises. Next up, the jovially marching "Karbon" may be Langer's vision of the indefatigable cycle of luxuriant vegetation as it sought to survive in the carbon deposits of this age. The LP finishes with a track dedicated to the Permian period. In retrospect, a certain conceptual rigor can be attributed to Tyndall's releases. A common thread runs through each album, allowing the tracks to unfold in sequence. On the one hand, the album borrows from classical notions, on the other, Langer's playfully impressionistic works. Durch Die Zeiten was the last record released by the Tyndall duo. Both musicians continued to make music, just not with each other. Rudolf Langer teamed up with Peter Preuß to found LAPRE. Jürgen Krehan released a number of new age albums as Nik Tyndall.
