After years of playing more commercial music, Hajo Teschner (voc, g) and Werner Klug (b) founded the band Silberbart in Varel, Friesland, in 1969. Soon after, drummer Peter Bahrens joined the band, replacing Gerd Bäker. Until then, the band had only performed as a cover band. With their now spectacularly loud and sometimes psychedelic hard rock, they gained a loyal fan base in northern Germany through numerous performances, sometimes as the opening act for well-known acts such as Organisation (pre-Kraftwerk), Frumpy and Eloy. In April and May 1971, the power trio recorded four songs for a demo tape.

Surprisingly, the major label Philips, headquartered in Hamburg, showed interest and bought the tapes. In the same year, Philips released the songs, recorded live under semi-professional conditions, as their debut album 4 Times Sound Razing in Germany. Their extremely progressive heavy metal with lots of improvisation, disturbing tempo changes, powerfully distorted guitars, raspy vocals and stomping rhythms, as well as noises and sound collages, was a psychedelic sound journey that found only few buyers. The group therefore split up at the end of 1972 for financial reasons. For many years, their first and only LP, designed by the Witt design studio, has been a sought-after collector's item, with a lot of money being spent on rare originals.
