Swedish Metal has really been having quite the moment. The past decade has seen Ghost elevated from underground arena rockers to literal arena headliners, a much-awaited Candlemass reunion, and the continued success of road-hardened stalwarts Opeth, Meshuggah, and Amon Amarth. Diehard fans of Scandinavian metal, particularly the more progressive and doom-oriented flavors, have been abuzz about Katatonia’s globetrotting shows.
