Unlike their debut album Osmose, the band Annexus Quam recorded their second and final LP Beziehungen as a five-piece. Werner Hostermann (cl, org, voc, perc), Jürgen Jonuschies (b, voc, perc) and Uwe Bick (dr, voc, perc) left the group and Martin Habenicht (bass) joined. This was accompanied by a radical change in their jazz-influenced psychedelic Krautrock. On this album, the band abandoned a fixed rhythm provided by drums and percussion. Instead, bringing free jazz to the fore with prominent tenor and soprano saxophones and the unusual use of the trombone in favour of a predominantly free and experimental improvisational style. The rich and unique instrumentation, including trombone, pan flute, electric zither, Spanish guitar, tabla, bendir, jaw harp and prepared guitar, significantly supported the avantgarde potential. In contrast to many German bands with their uncommercial and eccentric releases, which over time adapted their music to a larger audience, Annexus Quam, entirely committed to the avant-garde, became even more cosmic and free, without any formal structures.

Recorded in May 1972 at Studio Dierks, produced by Rolf-Ulrich Kaiser and released in the same year on the cult label Ohr, it was therefore one of the most extreme albums of free improvisation and was completely impossible to sell. After various performances and a tour in Tunisia, the group disbanded.
