the video description says they are the "originators of the Stoner/Desert Rock genre".
First of all, that's not a genre. It might be a style (even that is a stretch... desert style?), but it's not a genre.
If this music is desert style... then I'm gonna go out on a limb and say Soundgarden originated desert style because this just sounds like a bad Soundgarden cover band.
If you're going to be that pedantic about their classification, "stoner/desert rock" is a distinct subgenre when you consider that large collection of bands who share the same qualities while existing in completely seperate Venn Diagrams of Soundgarden, who were a grunge band from Seattle.
Unless this was your way of commenting on the rampant "subgenre-of-a-subgenre" labeling that goes on, but this is why people get so bent out of shape when people overgeneralize and (as an example) lump All Time Low and The Ramones in the same category of "Punk". Both bands with a penchant for fast, simple songs about girls via power chords, are they not?
