As I Am is a song by American progressive metal band Dream Theater, released in 2003 as the opening track on the album Train of Thought. The album was known for a heavier, more direct sound than much of the band's earlier work, and this track became a regular live staple and fan favourite. The excerpt circulates online as a short riff clip, shared by guitarists studying the tone and rhythm, and by editors looking for an instantly heavy metal moment without using a full song.
