Kraftwerk 2

Hütter later said of the album's recording: Nobody wanted to play with us because we did all kinds of strange things ... feedbacks and overtones and sounds and rhythms.

The lengthy, almost side-long "Klingklang" which opens the album is notable for its use of a preset organ beatbox to provide the percussion track.

It starts with a clangourous Stockhausen-like metallic percussion montage and gives rise to the unmistakable Kraftwerk sound.

The cover design, credited to Ralf and Florian, further hints at a deliberate association with conceptual art, being a repeat of the first album's pop art design – except this time fluorescent green replaces the red and the number '2' is added.

Kraftwerk has hinted that the album may eventually see a re-mastered CD release after its Der Katalog boxed set.
