Recorded sometime in the mid-'80s but not released until over a decade later, Neu! 4
picks up where the duo left off in 1975, exploring the extremes of both white noise and ambient beauty. Like Neu! 2
, the album fills out with remixes of the basic tracks, but where the earlier effort simply varied playback speeds, the material on Neu! 4
undergoes radical, even alien transformations. Much of the record predates 1990s electronic music with remarkable foresight: "Fly Dutch II" is a spacy techno loop which stakes out territory later claimed by Mouse on Mars
, "Danzing" is a brutal electro experiment, and "86 Commercial Trash" is constructed around samples from German television advertisements.
