Silberbart
Biography
Not much is known about this obscure trio from Hamburg, Germany who only released one record during their short existence. That album, 4 Times Sound Razing from 1971, is one of the lost classics of Krautrock, an album that combines proto-heavy metal energy with freeform improvisation.
Silberbart, whose name means Silver Beard, was formed in early 1971 by Hans Joachim "Hajo" Teschners on guitars and vocals, Peter Behrens on drums and percussion, and Werner Klug on bass. Teschners had been in a Shadows-styled band Die Schocker in the mid 1960s before moving from a small town to Hamburg in 1967 to join The Tonics, a group that did studio work, television work and even backed up on some LPs for the Philips label with a musical style that Teschner would later describe as, "everything that pleased and scratched nobody." When this group disbanded in 1970, Teschners, who had been interested in free jazz since age 15, was ready for something more adventuresome, and thus the experimental power-trio Siblerbart was born. With his connections with Philips he was even able to wrangle an album from the label.
The trio recorded the album in April and May of 1971, and the record, 4 Times Sound Razing, was released shortly after.
