Vinegar was founded by the three students Jochen Biemann (g), Bernhard Liesegang (b, voc) and Wolfgang Grahn (dr) in Cologne at the end of the 1960s and shortly afterwards expanded into a sextet with Dagmar Dormagen (voc, fl), Rolf Zwirner (g, vln) and Ralf Modrow (org, voc). In October 1970, they performed together with other groups from the Cologne area at a pop festival at the Photokina trade fair. There they were discovered by the son of label owner Werner Purrmann, who signed a record deal with them. Their debut album, recorded mostly live in the studio in just a few hours in January 1971, was released in the same year in an edition of just 1000 copies. The result was a psychedelic prog rock album that was reminiscent of early Pink Floyd in places. Complex and at times experimental hard rock mixes with raw krautrock, organ, violin and flute. The mostly instrumental pieces alternate with songs sung in English.
Unfortunately, it is Vinegar's only work. Due to personal differences and interests of the members, the band disappeared into obscurity shortly afterwards. Today, their first and only album is considered one of the most interesting treasures of German underground rock and is one of the most sought-after krautrock LPs by collectors.
