Neu! (pronounced NOY) was a German band formed by Klaus Dinger and Michael Rother after their split from Kraftwerk in the early 1970s!
'Neu 2' is infact the remix album to their self-titled 1973 album. On the alternative versions some are sped up or slow downed. The tracks range from delicate motorik driving tunes to heavy guitar-laden proto-punk stompers.
Considered the founding fathers of Krautrock!
