After nearly two decades of making all-instrumental stoner rock, San Diego trio Earthless unveil their first-ever album with vocals. Not content to merely slay the heads with his wah-wah-soaked six-string prowess, guitarist Isaiah Mitchell steps to the mic with a distinct Southern twang on the classic rock-flavored "Gifted by the Wind," the extended power boogie track "Electric Flame," and the sultry, slow-burning closer "Sudden End," while his bandmates lay down an endless groove for the ages.
