Impaler first appeared in 1985 with the release of the Rise Of The Mutants demo. The band's self-described shock rock would soon garner the band's press notoriety and the band would soon to Combat Records. The If We Had Brains... We'd Be Dangerous would further the band's extreme appeal and become the band's best-selling album. The band would soon lose Bob Johnson, but would add a second guitarist called John Stradinger. With Wake Up Screaming not doing brisk business the band would reconvene as Daddy Raw until 1994. Undead Things was essentially a new demo from the new line-up. Local label Root Of All Evil would reissue the band's music in 1998 and sign the band for new music. Court Hawley would rejoin in 2003. A DVD called 20 Years Undead was issued in 2004.
