David Randall "Randy" Blythe (born February 21, 1971) is the vocalist and lyricist of American groove metal band Lamb of God and side-project band Halo of Locusts. He also performed guest vocals for Cannabis Corpse, Overkill and Gojira. He is known as D. Randall Blythe on Lamb of God's albums. As a teenager, he looked up to the Sex Pistols, Megadeth, Bad Brains, Slayer, and Motörhead.
In June 2012, Blythe was arrested in the Czech Republic and was indicted on manslaughter charges related to the 2010 death of Daniel Nosek, a 19-year-old fan, after a Lamb of God concert. Despite finding that Blythe had pushed the fan off the stage, Czech courts held that the liability for Nosek's death lay with promoters and security members and acquitted Blythe of the charges.
