The band gained recognition following the 1986 release of their debut album, Tyrants of Teen Trash (Og Music), which led to an "underground" following in Europe, the United States (US) and Canada.
Taking their name from the scary neighbours on TV's The Flintstones, the Gruesomes developed an image of matching black turtlenecks, Beatle boots and bowl haircuts, combining it with a "snotty" punk musical style.
Early live shows relied more on the group's energy and humour than actual musical ability; however, the Gruesomes proceeded to become a popular club act, despite their inexperience.
