✦✦✦✧ This sixth album from The Sword continues the band’s progression from frantic Mastodon territory to more of a laidback Earthless vibe, while giving us the band’s most cohesive sonic landscape since 2010’s “Warp Riders.” If anything, “Used Future” marks a doubling down on the band wearing their 70s and 80s influences on their sleeves (there are obvious nods here to Santana, Skynyrd, John Carpenter, Pink Floyd, The Dead, etc.).
