Mark Snow (born Martin Fulterman; August 26, 1946) is an American composer for film and television.[1][2] Among his most famous compositions is the theme music for science fiction television series The X-Files.
^According to the "Behind the Truth" segment on the X-Files Season 1 DVD, Mark Snow created the echo effect on "The X-Files" theme song by accident. Snow said that he had gone through several revisions, but X-Files creator/writer/director Chris Carter felt that something was not quite right. Carter walked out of the room and Snow put his hand and forearm on his keyboard in frustration. Snow said, "this sound was in the keyboard. And that was it."
