If you like NEU! you should listen to Harmonia, which is the two guys from Cluster plus NEU!'s Michael Rother on guitar. Their second album, Deluxe, is my favourite.
Not a huge fan of the genre, but I did see Tangerine Dream’s show at Berkeley in 1988 that became the album “Rockface”. They had a full-blown laser show that was really cool, plus the added bonus of Andy Summers as the opening act.
It started as a derisive term in the British rock press, and really took off after being co-opted by Faust when they used it as the title for the epically grating opening track from Faust IV (also the source of the two Faust tracks I linked to above).
It is indeed. Unfortunately, the three albums that preceded it are not. I love the song “Autobahn” to death (long version, please), but my favorite Kraftwerk album is the third, Ralf und Florian, which is a wonderful bridge between the experimentalism of the first two albums and the cheerful pop of Autobahn et seq.
Their Autobahn album is the only thing I know about them. I don’t even remember exactly how I came into possession of that 8 track. I think it may have been a free gift from a record club (anyone remember those?).
