pre-junior high: first some embarassing shit then iron maiden, bruce dickinson
junior high: dark tranquillity, in flames, tiamat, at the gates, katatonia, emperor
high school: same as above + burzum, enslaved, agalloch, ulver, helheim, darkthrone, skepticism, thergothon, candlemass
later: same + everything else i like now
i cant name single bands or even two or three
there are specific songs that make me think of earlier periods in my life but i have not really abandoned anything i like since i got into metal when i was ~12. i still like most/all of those bands to some extent at least, so the bands as such are not really connected with a time period for me. the only thing is i kind of stopped caring about thrash metal, i had a THRASH METAL YEAH DENIM AND SPIKES UPP UR BUTT period but these days not so much
