Finland mentioned! Therefore I just had to listen to this live album. The performance in question was recorded back in 1971 on the annual Finnish rock festival in Turku that is called Ruisrock (translates literally as Rye Rock), but the live album was only released recently in 2008.
I don’t know whether it had something to do with the quality of the recording, but it turned out to be just noise for the most part, even if a pleasing noise of a sort. Yet the noise had reached its momentary perfection during the guitar solo in Uncle Harry’s Last Freakout, where the distortion levels just killed my ears, but the experience was definitely worth all the damage taken. Listen to it at your own risk! For a quick access to the ear killing part you can scroll to 8.20 in the song.
