"Darkness Within" is a single by American heavy metal band Machine Head, from the 2011 album Unto the Locust.

35 on the Billboard Mainstream Rock chart, the band's first entry and highest position.

The video for "Darkness Within" was filmed in Prague, Czech Republic.

Guitarist and vocalist Robb Flynn explained this choice:[3] "The first time I visited Prague was on the Burn My Eyes tour cycle in 1994 as support to Slayer.

The baroque and gothic architecture, the religious symbolism everywhere, the Charles Bridge, St. Vitus's cathedral, but also the Eastern Block feel it still carried, it was one of the most unique and beautiful cities I'd ever seen and still is.
