'Darkness Within' is one of the softer songs from Machine Head's 2011 album, 'Unto the Locust.' Released as a single in 2012, 'Darkness Within' captures the entire range of Machine Head's sound.

From soft, to crunchy, to blistering, the song is a pillar that holds 'Unto the Locust' so high in the opinion of metalheads. To many, the song can be summed up in two simple lyrics -- Music is my savior / Save me.
