but seriously. to be fair hardly anyone can stand the vocals when they first approach BM, and he suggested there's a chance he could get into them. totally agree with aeternus. i think some good starters for people already into melodic stuff are:
aeternus - and so the night became
graveland - the fire of awakening
nokturnal mortum - goat horns
varathron - his majesty at the swamp
summoning - dol guldur
personally i fell in love with BM and BM vocals the first time i heard 'hvis lyset tar oss', but i know a lot of people who've struggled to do the same.
