We've been digitally transferring all of Kraftwerk's original recordings and sound sources from our badly degrading master tapes while our engineers, Fritz and Henning, have been working in parallel to remaster our early albums for re-release.

We would complete a song and then move forward, always keeping very focused on one Kling Klang project at a time.The sound needed remastering… it’s like a reconstruction, like when a painter takes his paintings from the archives and blows the dust off and puts them in a retrospective.

An actual release date was not announced and the project remained unreleased for years, despite having a page on the Kraftwerk website during this time.

The individual remastered albums were eventually made available on compact disc in October 2009, while an 8-CD boxed set and heavyweight vinyl versions followed in November.

[3][4] Due to licensing restrictions imposed by Warner Music Group, the albums Computer World, Techno Pop (formerly known as Electric Café) and The Mix have only been made available in the US from Astralwerks Records as a part of the box set, or individually as imports (the iTunes Store also carries the complete remastered catalogue as well).

Looking back, it's remarkable how concise these albums are, averaging around 40 minutes and seven songs each, as is the fact that such feats were achieved by purely analogue means.
