I'm not even sure what the "relatively obscure" artists would be this round, tbh.
I want to say UFO but that might just be me not being old enough.
Of the artists sent this round, I'd say the "relatively obscure" ones are Alter Bridge, Beyond the Bridge, The Hirsch Effekt, Katatonia, Amorphis, and UFO. That's just because I've rarely/never heard about these bands before this roulette.
Ehhh, I honestly don't blame you for that. Unless you follow wrestling 10-15 years ago or follow Slash's solo band, you probably wouldn't know them. They rarely get plays on Sirius XM Octane (which is supposed to be the go-to station for a band like them to get radio airplay) unlike their more well-known contemporaries (which I won't list here since it may be a future submission). The band, that 3/4ths of the guys used to be in, had their popularity peak roughly 2-3 years before you were born.
Honestly, I'm quite amazed how this band is still alive and relatively surviving well for 16 years, when many other alt metal/nu-metal/post-grunge bands that started around the 2000s seemed to fade to obscurity. I'm still amazed on how I'm still a big fan of theirs for 13 of those years when many bands I've discovered back then, I don't like as much now.
