Most Americans don't know who Kraftwerk is, but, being stationed at Rammstein, I got to hear them a lot.
Personally I think this is a bit of a let down, but maybe this will be the album that will break them in The U.S.
Of course they'll have to edit Autobahn down to a five minute song to get radio airplay, but, if they can do that, then they'll be a huge hit stateside.
