In case you weren’t paying attention, last year Mastodon unveiled Crack the Skye, an album so cohesive that they’ve been playing it in its entirety for their last few tours. Now a lot of the secondary markets that didn’t get to see them perform it live will get a chance to, and they’ve lined up some pretty stellar openers as well. Starting on April 16, Mastodon will be joined by Between the Buried and Me, Baroness, and Valient Thorr for a month-long tour. Dates will be listed below.

Also, while the lineup for the New England Metal and Hardcore Festival has yet to be announced, the tour’s 4/23 stop at the Palladium in Worcester means that the Fest has its Friday night headliners lined up.

In other news, if you’ve been holding off on picking up Mastodon vinyl, April is your chance to make up for it. They’ll be offering a new limited tour-only color vinyl of Crack the Skye, and on National Record Store Day (April 17 this year), they’ll be reissuing vinyl editions of Blood Mountain in both standard and deluxe editions. The deluxe will be pressed on double 45 RPM discs on 180 gram vinyl in a gatefold sleeve featuring new custom art from Paul Romano. Dates after the jump.
