Earth is an American musical group based in Seattle, Washington, formed in 1989 and led by the guitarist Dylan Carlson. Earth's music is nearly all instrumental, and can be divided into two distinct stages. Their early work is characterized by distortion, droning, minimalism, and lengthy, repetitive song structures. The band's later output reduces the distortion while incorporating elements of country, jazz rock, and folk. Earth is recognized as a pioneer of drone doom, with the band's Earth 2 regarded as a milestone of the genre.
