Just my two cents: Remember around 2013 ish when there was way too many powerviolence bands and it the sound started to get bastardized as the fast parts were just thrown in as space filler between ridiculous breakdowns? It seemed like anyone who would have been listening to metalcore or beatdown was just playing with power violence as the genre du jour.
I'll have to listen again, but on first one or two listens, Gulch seemed like the same thing being applied to the more recent trends in hardcore: d-beat and stompy floortom hardcore (Glue, SHIT, Bib, etc.). Like on the surface level it's trying to have ties to the punk side, but the focus is way too breakdown based.
While I'm throwing out dumb opinions, I also feel like Gag are easily the worst of that wave of stompy hardcore with semitone riffs. Glue and SHIT seem(ed) to do similar stuff just way better (to my ears, opinion, opinion...)
