Ok, now that we know Kraftwerk can exist without Florian, we are open to pretty much any surprises, aren't we? This very recording was made during that short period of time when Ralf himself was not a part of the band in summer 1971. The concert lineup reminds more of Neu, considering Michael Rother and Klaus Dinger are together on stage with Florian. The recording was made at the Gondel Kino in the city of Bremen on June 25, 1971. Some kids giving names to the tracks on the bootleg CD were not exactly the fans of Kraftwerk at all, otherwise they would give tracks their real names, instead of "K1", "K2" et cetera. But there's one non-album there, called "Heavy Metal Kids". Not a bad one for a Kraftwerk track title, eh? To be honest, I don't think they intended to give this track such a name, it's either a working title or somebody else's dream. But not only that. You might think it was created by somebody else, too. It's in the mood of the first two Kraftwerk LPs, yet still it is hard rock!? Like, the real one, with guitar riffs and solos. Very strange and interesting record.
