The band were the source of some controversy due to their deliberately offensive lyrics. Scott Ian described the songs on "Speak English Or Die" as "ridiculous" and "just a big inside joke", adding: "Some people thought we were racist, and those people are stupid." Bassist Dan Lilker stated: "The lyrics were never intended to be serious, just to piss people off." The band had several periods of inactivity following their formation in 1985. According to singer Billy Milano, the 24-song extended play of live and unreleased material called "Rise of the Infidels", released in August 2007 on Megaforce Records, "will finally be the last of S.O.D.," laying to rest rumors of another reunion.
