2013 has been a genuinely stellar year for music, with some massive releases across all genres (I could spend a whole day writing about how much I love ARTPOP, but I'll save that for another time). In this piece, I am going to focus on the biggest and best releases to stem from the genres of rock and metal - I state both titles because the albums in this list span from the mainstream, more pop-sounding rock bands to some of the most extreme, brutal grindcore to ever be recorded. If you're wondering what grindcore is by the way, it's exactly how it sounds... So join me, as I take you through the Top 10 rock and metal albums to be released this year (in my humble opinion, of course).
