I need to spend some time in this thread as I've recently fallen in love with the heavier sounds. I thought I missed the boat since I didn't like it as an angsty teen, haha, but what do ya know!
An old friend introduced me to Author & Punisher, and this video is hilarious!
Edit. I'm going through some Brazilian metal bands on youtube and I have to say, I wish more of them sang in Portuguese as opposed to English.
