My one was
Back then, I was so obsessed with drums. If an album had killer drumming and a really fast tempo, I bought it instantly. Everything else was secondary.

I remember being puzzled by the vocals, though; they were so unrecognizable, monsterlike. But I didn't care, as long as the drums were on point.... and here they where/are PERFECTLY.
Later on, when
Obituary dropped their debut
Slowly We Rot, I put on the opener, 'Internal Bleeding.' Whooosh! That was some real heavy sh_t!
I vividly remember after i bought the album my grandma walking into my room at the
exact moment the vocals start kicked in. She was absolutely
shell-shocked. Seeing her face .... and ARGH! ...that was priceless!
My grandma was cool about it, but my mom? Not so much. She used to say, 'Why do you listen to such aggressive music? It just makes you more aggressive!!! (waaah waaah waaah) She never really understood me.
In reality, that music saved me. It was a way to vent the 'aggro' emotions I had back then. You dive into the stream of the song with 100% raw emotion, and by the time you stop listening you feel relaxed.
