So, Cold Dark Place is actually a thing! Back, when Mastodon were writing Emperor of Sand, there was talk about a double album, with the second half being written entirely by Brent Hinds. That obviously didn't happen, as EoS ended up being a single record. Then, in the best interview ever made (check it out below), Brent said an album called "Cold Dark Place" will be released "on Record Store Day in June". The record is supposedly about a "nasty breakup". Brent described it as "pretty dark, beautiful, spooky, funky, ethereal, melancholy music, which also sounds like the Bee Gees a little bit."
Emperor of Sand is the seventh studio album from American progressive metal band Mastodon. The album was recorded at the Quarry in Kennesaw, Georgia and mixed at Henson Recording Studios in Los Angeles. The band worked with record producer Brendan O'Brien, who they collaborated with on their 2009 album Crack the Skye. The songs were recorded as originally arranged, then they revisited each track to edit and refine the sound. Drummer Brann Dailor completed his drum tracks and began drafting lyrics while guitars and bass were being recorded by other band members. Scott Kelly of Neurosis and Kevin Sharp of Brutal Truth both appear as guest vocalists on Emperor of Sand. Kelly has appeared as a guest vocalist on every Mastodon studio album since Leviathan (2004).
Mastodon - Blood Mountain (2006). After springing into existence fully-formed with the progressive post-sludge (or whatever) of Remission, Mastodon injected more melody and ambition into its accomplished and worthy follow-up, Leviathan. Their proggy tendencies became even more prominent on Blood Mountain. Released on September 11, 2006 in Europe and the day after in North America, Blood Mountain did extremely well. Total Guitar ranked it the number one album of 2006, while magazines like Kerrang! and Metal Hammer thought it was just was epic as Leviathan, if not better. It was also featured on many websites' and magazines' 2006 countdowns. It was also Mastodon’s third highest debut on Billboard 200, at #32, behind Crack the Skye and The Hunter. Guitarist Bill Kelliher considered this album to represent the earth element, and at the time, bassist Troy Sanders said it was "sonically the best album we have done"…
With an ageless magnificence and rich musical imagination, Mastodon unleash Leviathan, an unabated testimonial to the band's earthshaking ability to rock. Their thundering musical muscle, talent and vast sea of ideas triumphantly unite on Leviathan, delivering heavy, organic music that melds exhilarating ambitiousness with a well-honed accessibility.
