Advent.
I found a CD in a friend's collection that had the coolest cover... EVER! And, it had a sticker that said it was 66 minutes in 5 tracks of the best metal I would ever hear. I was getting deeper and deeper into metal at the time, and when Advent began spinning, I was shocked to hear acoustic guitars and they blew me away. I came back home and the record store didn't have Morningrise, so I got MAYH. Opethian from then on...
