M83 (named after the spiral galaxy "Messier 83") is electronic artist Anthony Gonzalez. Gonzalez and former member Nicolas Fromageau founded the group in 2001 in Antibes, France. M83's style owes a lot to the shoegaze genre, in that there is much emphasis on tonality, extensive use of reverb effects and often softly-spoken lyrics at times submerged in instrumentation.

All five of M83's albums were well received, in particular Dead Cities, Red Seas & Lost Ghosts, their second album, which allowed them to break through to a larger audience. For the third album released by M83, Before the Dawn Heals Us, Gonzalez decided to part from Fromageau (after an emotionally distressing tour for Dead Cities) and record on his own.

M83's song "Unrecorded" from Dead Cities, Red Seas and Lost Ghosts was used in the trailer for the American release of the Russian movie Night Watch, and the track "Teen Angst", taken from "Before the Dawn Heals Us", appears on the trailer for the film adaptation of Philip K. Dick's novel A Scanner, Darkly", which was released in 2006.
