Rosetta was founded in Philadelphia, Pennsylvania[1] by vocalist Michael Armine, bassist David Grossman, drummer Bruce McMurtrie Jr., and guitarist James Matthew Weed.

"[3] Their debut album, The Galilean Satellites, featured two separate hour-long discs (one of more metal-oriented music, and one of ambience) that synchronize together.

After a full United States tour in July, the band's second full-length album, entitled Wake/Lift, was released through Translation Loss on October 2.

Guitarist and vocalist Eric Jernigan, who contributed guest vocals to the band's previous two albums, became an official member of Rosetta in 2014.

Two EPs, Sower of Wind and Terra Sola, were released in 2019, as was a split with Labirinto and La Bestia de Gévaudan.

Rosetta plays a style of post-metal[7] that incorporates elements of space rock, sludge,[1] post-hardcore,[8] shoegazing, drone,[1] post-rock, avant-garde and ambient.

[2] Rosetta's members have an interest in astronomy and space travel, and they somewhat humorously describe the band's music as "metal for astronauts".
