Well this is interesting! Meshuggah and Mastodon have been confirmed for the 2014 Bonnaroo Festival that will be taking place on June 12th – 15th in Manchester, TN. The festival revealed it’s lineup last night, and to our surprise, these two metal heavyweights are on it! Okay, Mastodon did play the festival back in 2008, but can you imagine the crowd’s response to Meshuggah?! They are going to absolutely destroy that place! I might go just to see the Elton John fans running for their lives! The lineup is diverse as hell, like it always is, but it might just be worth a trip to catch these two metal forces annihilate everything in sight in Tennessee!
