City of Evil is the third studio album by American heavy metal band Avenged Sevenfold, released on June 6, 2005, through Warner Bros. and Hopeless Records. Co-produced by Andrew Murdock, City of Evil contains a more traditional heavy metal and hard rock sound 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 fry 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.
