Ok, I think it was 1995....
At that time I just hated growlings and stuff, it was all bands like Cannibal and Deicide which to me drowned in the same dull senseless growling!
A friend of mine (I think we all have this friend sharing with us some potential knowlege huh?) gave put the promo for At The Gates - Slaughter Of The Soul. I nearly pissed my undies. I thought...arghhhhhhh damn cool!!! what did you said the name of the band is????
Few days later I boomed myself to the stores and I say to the man there, hey give me At the Gates, the new stuff. He said he hadn't got it yet, it was about to be released but not yet, and then (as we normally do when we don't find what we're looking for) said, "well have you got something like that" he said (thunder striking at the rear....) "hey lad, I have this some days ago, it's a minicd from this band Dark Tranquillity" I thought, what a shitty name (never been so wrong) and then he showed up Of Chaos and Eternal Night. I bought it and as phyros say, "hell yeah!" it shocked me, since then I bring them with me.
But still normal growlings I dislike a bit. i.e. at the gates fisrt works are boring and dull to me, specially gardens of grief, and also the demos from DT, but well who am I to say....I'm just a melon
So basically ATG adn DT opened my way to the growling world
