Found this lurking on the net. The best quality Kraftwerk recording I have ever heard (full stereo, sounds like mix desk / soundboard / FM broadcast). Also note unique 'short' versions of Autobahn and Etape, and a wonderfully irreverant version of "Numbers". Oh, and the recording is only 16 days old.
 
Now, should anyone want to reward my finding this link, I would be grateful if you could point me in the direction of MP3's of any of the following :
 
Karl Bartos 2003/2004 concerts
Autobahn 1973 7"
Music Non Stop 1986 7" or 12"
Telephone Call 1987 (any remixes at all)
