Bob and Blaise, two guys, seem to have gathered together with maybe an autoharp, an open piano, a drum kit, some gongs, a marimba, a flute, some tubular bells, maybe a clarinet or something, and I am guessing some weed. And they improvised some noise. They are pretty good at uttering non-sense phrases. My guess would be this was recorded on a boombox because it just seems like the tape auto-reversed and kept recording.
It sounds like someone released some pre-modern people in a room with a bunch of instruments and a gas that eliminates all inhibitions. So they whack on a bunch of things in a way that has no goal seemingly, but to make random noise. There might be a third guy in there too. It has a childlike, pre-historic feel. They seem to be searching for happy accidents. They find a lot of accidents.
I wish more non-musicians would try to do things like this. These guys are passingly familiar with meter, time, rhythm, and harmony. And they have released themselves from any instinct to make "sense." It has a sort of dreamlike content. It might be something good to play while trying to go to sleep.
