During the mid-'70s, Germany's Kraftwerk established the sonic blueprint followed by an extraordinary number of artists in the decades to come. From the British new romantic movement to hip-hop to techno, the group's self-described "robot pop" – hypnotically minimal, obliquely rhythmic music performed solely via electronic means – resonates in virtually every new development to impact the contemporary pop scene of the late- 20th century, and as pioneers of the electronic music form, their enduring influence cannot be overstated…

When the Bureau B label contacted Karl Bartos and showed interest in releasing any archival material he might have laying around the lab, the former Kraftwerk member (that is, "classic lineup" member, joining for the Autobahn tour and leaving somewhere between Electric Cafe and The Mix) wasn't interested. After all, he's a never-look-back futurist, but as the liner notes to Off the Record explain, he's an open-minded futurist as well and allowed this initially rejected idea to morph into something new.
