Richard Francis "Rikk" Agnew, Jr. (born December 9, 1958) is an American guitarist. He has played in some of the most influential bands of the Orange County hardcore punk scene, as well as the influential deathrock band Christian Death.
With Casey Royer, Agnew played in Social Distortion and the Detours in 1979. He joined the Adolescents in 1980. His guitar style and writing dominated the Adolescents' Blue Album, released in May 1981 on Frontier Records. Agnew left the band soon after the album's release due to personal and creative differences.
Later in 1981, Agnew joined Christian Death, writing and playing guitar on the seminal Only Theatre of Pain album, issued by Frontier in March 1982. He also performed on the band's Deathwish EP, recorded before the album during the sessions for the compilation Hell Comes to Your House but not released until 1984.
In 1982, Agnew released his first solo album, All By Myself (Frontier), on which he played all of the instruments.
He joined D.I. in 1983, playing on their 1983 debut EP Team Goon (originally known simply as D.I.) as well as their first two albums, (1985's Ancient Artifacts and 1986's Horse Bites Dog Cries), before deciding to leave the band in 1987.
