That’s Ween. Two talented high-school buddies who (by many reports) have steadfastly refused to do the kinds of music that sell lots of records. Mushrooms are (by many reports) a contributing factor.
That’s Gwar. I could describe them but I think you get the picture. This is a relatively tame video for them. Frequently (by many reports) they spray their audience with faux bodily fluids.
Ween, Gwar, they do their own thing. They’ve done it for decades. Whoever likes it likes it.
