Wacken without end! :-) To all those how'd like to fresh up the memories of this years Wacken Open Air the german TV station NDR will help you out.
They will broadcast shows from Wacken 2012 (Graveyard, Leningrad Cowboys and Saxon) as well as a documentary report entitled „Heavy Metal trifft Karniggels” on September 14th 2012 on TV (starting time 21h in germany) and via internet on their Wacken subpage. After the stream the documentary has been annouced to be available as a free stream on demand divided into several small sections that will remain on the linked website. Actually there's already a talk with the director of the documentation online here.
To find your personal starting time of the stream I've discovered a fine website. Just click here and it will show you a selection of countries so you'll easily be able to find the correct time for your timezone. :-)
Update 2012-10-19: Meanwhile the documentary has been uploaded to this location. Having taken a look at the stuff it seems to me that the documentary stuff has been left in but the videos from the band performances have been cut away. Guess that's because of legal rights missing to stream this stuff. Anyway, nice they did put this one up at least as flash videos and additionally also as Windows Media Stream in three qualities.
