Recorded live during an "illegal" festival in a district of Stockholm in 1970, this is a pretty incredible document of one of swedish underground's most important representatives. All of it was taped by a fan in the front row and it actually sounds great. Of all the group's recordings, this is, without a doubt, their heaviest set. The lo-fi quality of the recording just adds warmth to the concert (the weather was apparently quite shitty that day, it was raining and cold - but you can't hear it here). The two covers found on their first release is played again (and Satisfaction sounds even heavier this time!!!). Lifeforce #3 is a new track and it's quite good, a long and intense jam. If you don't mind the recording quality (it might sound great, but a professional recording this is not!), this is a great place to start.
