Formed in 1989 in Washington state, Earth are pioneers of drone. Led by Dylan Carlson, Earth’s music is largely instrumental, crushingly slow and heavy, and repetitive.  More recent Earth output introduces elements from completely different styles of music. Carlson, Earth’s helmsman, has noted influences as far ranging as British folk bands like Fairport Convention and country singer Merle Haggard. Their most recent album, Primitive and Deadly, is the first Earth album since 2006 to include vocals. Drone on at their first MDF appearance.
