ill specifically talk about some stuff that i dont find to be incredibly popular! recently ive been listening to DAI DAI DAI, a japanese girl group making digital hardcore theyre really underrated and good (specific song id recommend is oh happy die) strapping young lad is like my favorite metal band and i dont see that many people talking about them (specific song id recommend is oh my fucking god) also recently found destiny potato, another one of those post hardcore bands that only have one album but the album is really good and the lead singer is a girl (rare)
also if you're at all familiar with mike pattons work, PLEASE LISTEN TO TOMAHAWK. even if you dont know him listen to tomahawk anyway. i cant even think of one single song to recommend cus i like them all. self titled and mit gas are the best albums to look at
i could keep going on forever so ill stop myself, but heres some other stuff i really like(some more well known whan others): the mars volta, stomach book, a lot like birds, gangpol und mit, secret band, thank you scientist, mytishchi on fire, dog fashion disco.....these are all like completely random things i guess just pick which name sounds the most interesting to you
