Grimble Grumble formed in 1995, taking their name from a character mentioned in the Pink Floyd song "The Gnome".[2] Prior to this, bassist Christine Garcia and guitarist Reuben Rios had been playing together in South Chicago's Slag Valley since they were teenagers in the late 1980s.[3] The group's first release was a split 7-inch record with The Azusa Plane in 1996, and several more singles and EPs followed in the late 1990s. A self-titled compilation of two of the band's EPs was released in 2000, shortly before the group went on hiatus.[2]
In 2004, Grimble Grumble regrouped to record Leaves Leader,[4] which would be their last recording for seven years. The group toured intermittently[5] until 2011's September Sun. A tour of the United States followed in 2012.[6][7]
