"Beast and the Harlot" is a song by American heavy metal band Avenged Sevenfold, released as a single from their third studio album, City of Evil.

[citation needed]Total Guitar wrote: "The main riff to Beast and the Harlot is a great piece of dropped-D riffing with Zacky and Synyster cleverly placing the second part of the riff across the beat to create an aggressive syncopated feel, once again avoiding all the usual metal clichés."

[8] A live version recorded during Warped Tour was featured as the B-Side to "Bat Country",[9] as well as on the Masters of Horror soundtrack.

On Avenged Sevenfold's All Excess DVD, Tony Petrossian, who directed the video,[13] says that M. Shadows' lyrics for this song about the fall of Babylon is comparing Babylon to Hollywood,[6][14] showing many Hollywood clichés such as the young, innocent boys being corrupted and losing their souls.

The Rock Band 3 version of the original master recording of the song being notable in that it has support for Rock Band PRO mode, which takes advantage of the use of a real guitar / bass guitar, along with standard MIDI-compatible electronic drum kits / keyboards in addition to up to three-part harmony and/or backing vocals.
