David Randall Blythe (born on February 21, 1971) is the vocalist of the band Lamb of God.

Randy Blythe joined Lamb of God, formerly known as Burn the Priest, in late 1996. The band wanted to retire from its original instrumental sound. His vocal style consists of deep 'growled' vocals, shrill screams, and recently baritone singing. He occasionally uses short quips of prose to outline the band's 'mission statement.'

Randy was featured in a handful of his peers' DVDs, such as Killswitch Engage's '(Set This) World Ablaze' and Machine Head's 'Elegies'. Randy was also featured in Metal: A Headbanger's Journey, and Melissa Cross's 'The Zen of Screaming.

Randy's haircut is known as the 'Devilock' and it was created by Glenn Danzig, Doyle Wolfgang Von Frankenstein, and Jerry Only, all members of one of favorite and influencial bands the Misfits

Randy has a small tattoo on his hip that resembles a penis and two testicles. According to Randy in Killadelphia, it was the result of him trying to tattoo the Misfits logo on himself while drunk and passing out before he could finish it.

He also has a tattoo on his left forearm reading COBHC standing for "Children Of Bodom Hate Crew" which is the name used by the band Children of Bodom for themselves, their crew, and all of their fans.[citation needed]

Randy also has a side project band known as Halo Of Locusts.

In late 2007 he worked with the heavy metal outfit A Life Once Lost on their album Iron Gag. He provided additional vocals on the track "Pigeonholed" as well as helped in the vocal processing of the track. He also appeared on the song "Skull and Bones"" by the band, Overkill.
