Established in 1998 by Berlins DJ/Producer team Jazzanova, SONAR KOLLEKTIV is a pool of record labels: Dialog, Airdrops, No Zession, Recreation, Mermaid, Best Seven, Hot Drops & Aspekte Schallplatten - each label`s musical direction and colour is influenced by the label`s head. The task of Sonar Kollektiv herein is to take care of administration and coordination, thus giving musicians, artists and DJ�s the possibility to carry out their own ideas without having to bother about the technical and business compulsions implied by the music market. Moreover, Sonar Kollektiv includes a PR-agency called hallama.org, a booking company called ranking. and a graphic department called Jutojo. The Kollektiv should give the artists the possibility to organise and push their musical life.
