[2] Chief Kraftwerk members Ralf Hütter and Florian Schneider used two drummers during the recording of the album; Andreas Hohmann and Klaus Dinger.

[citation needed] The other instrumentation features Hütter on bass and Hammond and Tubon electric organs, the latter was made by Swedish factory Joh Mustad AB in 1966,[5][6] whilst Schneider supplied flute.

[9] The 3-member Kraftwerk line up of Schneider, Dinger and Michael Rother made an appearance on Radio Bremen,[10] and also on the TV shows Beat-Club and Okidoki.

[11] After this, Dinger and Rother left to form revered band Neu!, with Hütter rejoining Schneider to continue Kraftwerk and both parties recording under the mentoring of Conny Plank.

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