A double helping of Can, one (relatively) bite-sized, the other a full feast.
For starters, a 1970 performance of Paperhouse, all long hair and intense focus on their respective instruments, with the additional appeal of Damo and Holger bare chested, though I suspect the latter may have a very specific target audience.
For mains, reportedly the earliest full concert recording of the band (I haven't fact checked this claim). From November 1970, this is eighty-four-and-a-half minutes of Can live from Soest, Rockpalast, Germany, broadcast on the TV show Karussell Für Die Jugend (Youth Carousel) in glorious monochrome.
Apart from a few sullen individuals, the audience appears to having a great time, and no wonder. I wasn't even born when Can played this gig, but their music subsequently caught up with me.
