Mastodon have spent over two decades reinventing modern metal. Their ability to fuse sludge, progressive rock and alternative metal has made them one of the most visionary bands of the 21st century. Masterpieces such as ‘Leviathan’, ‘Crack the Skye’ and the introspective ‘Hushed and Grim’ showcase their constant evolution, with each album becoming an emotional and sonic voyage. With multiple Grammy nominations and a sound balancing the visceral and the ethereal, Mastodon come to Rock Imperium Festival as true alchemists of riff and atmosphere.
