Today GRAMMY® Award-nominated metal titans Lamb of God and GRAMMY® Award-winning band Mastodon announce the co-headlining Ashes Of Leviathan Tour. The tour finds the two iconic bands join forces to celebrate the 20th anniversary of two seminal releases: Lamb of God’s biggest-selling album Ashes of the Wake and Mastodon’s acclaimed sophomore album Leviathan, which were both released on August 31, 2004.
