Affenstunde

Originally released in 1970 in Germany by Liberty Records, it has been reissued several times by various international labels.

The 2004 German SPV edition features one previously unreleased bonus track.

"[3] Perfect Sound Forever described Affenstunde as "a landmark electronic album" that "also doesn't have the timeless quality of many of their later works".

[1] Julian Cope described it as "a debut album of incredible sounds and sensations that were unlike anything prior to its existence".

[4] David Stubbs described the album as sounding "otherworldly, beguiling, perhaps precisely because of its 'datedness', its raw technological naïveté".
