City of Evil is the third studio album by American heavy metal band Avenged Sevenfold, released on June 6, 2005,[10] through Warner Bros. Records. Co-produced by Andrew Murdock, City of Evil contains a more traditional heavy metal and hard rocksound than Avenged Sevenfold's previous two albums, which showcased a predominantly metalcore sound. The album title is derived from a lyric in the song, "Beast and the Harlot". The album is notable for the absence of screaming vocals. M. Shadows worked for months before the album's release with vocal coach Ron Anderson, whose clients have included Axl Rose and Chris Cornell, to achieve a sound that had "grit while still having the tone". In order to increase stamina and strength on the pedals, The Rev would sit for hours practicing until he could get up to 210 beats per minute.

The album contains some of Avenged Sevenfold's most popular and famous songs, including "Bat Country", which is arguably their most successful to date, being one of their two singles certified Gold by the RIAA. City of Evil was very successful after its release, debuting at number 30 on the Billboard 200 chart and certified as a platinum record by the Recording Industry Association of America in August 2009.
