In this issue of Metal Hammer, we chat to Slipknot as they prepare to unleash their most surprising album in two decades. We catch up with Ozzy to talk about his brilliant new album, Patient Number 9, and Gloria Cavalera tells us how she taught herself band management and steered Sepultura to world domination.

As Dirt turns 30, we ask some of our favourite artists including Kerry King, Lzzy Hale, Jeese Leach and Scott Ian to explain why they love Alice In Chains and to name their favourite track. Electric Callboy have gone from youth centres to stadiums in the blink of an eye, so we nip over to Germany to find out how the hell they pulled that off, and we also travel to Portugal to talk to rising black metal stars Gaerea about tourism, creepy masks and, er, burning people alive.

Okaaaaaay... moving on... We hit the studio with Enslaved, Imperial Triumphant’s Zachary Ezrin invites us into his record collection, and Dave Lombardo answers your questions. Skindred’s hyperactive frontman Benji Webbe sits still for just long enough to give us his life lessons, Incubus relive the making of A Certain Shade Of Green, and 10-year-old Harper tells us how she scared the crap out of the America’s Got Talent judges when she let rip with Spiritbox’s Holy Roller.

All this, plus all the essential news and reviews from the world of metal.
