Rosetta

Rosetta is an American post-metal band from Philadelphia, Pennsylvania incorporating elements of post-hardcore, shoegaze, drone, post-rock, avant-garde and ambient, with influences as diverse as Neurosis and Isis, My Bloody Valentine, Frodus, and Stars of the Lid.
The band somewhat humorously self-describes its music as "metal for astronauts", and its members are very interested in astronomy and space travel.
