This one actually is rather quirky yet relaxing at the same time and hearing this recording was done long ago is rather impressive seeing the recording survived this long. At the start it sounds like someone hitting something a lot on the drums aside from the pedals, probably from how loud they are kicking the drums.
Also heard near the start is what seems to be that thing on the back of doors that when hit makes a loud twanging reverb sound. Like how the vocals near the start sound a little orgasmic making the jam kind of funny actually.
The guitar part is really sweet on the ears and around 2:30 the guitar tune slightly makes me think of "Battle with the Masked Man" from Mother 3, strange how two different songs can sound so similar sometimes.
Around 3:20 the tune slightly reminds me of Barracuda for some reason yet slower and a different build on the rhythm. Really nice little solo too. The bass groove makes that part sound really good. What kind of bass guitar was being used?
Around 6:35 another slight solo and then no guitar for a moment. Kind of sounds like I am hearing water for a moment.
At 7:30, actually like that clicking sound, makes me think of a cowbell. Then the drums kick back into full rhythm while the guitar also slowly comes back in with a mellow tune that just sounds all around relaxing.
At 8:50 the drum beat sounds pretty awesome and the bass rhythm sounds familiar to another song but I can't quite come to what the name of the song is. Then around 11:00 the guitar picks up a really quickening pace that switches between some long held notes and some fast strumming which is enjoyable.
At 12:10, kind of sounds like the vocalist was saying "shh" and then the random "haaaa". Really liked the drum solo since it seemed to have a tribal sound to it.
Then the final minute is just a slow down and grind as the song ends.
Overall, very interesting and nice to hear jam session.
