Earlier they performed in English by the name Lost Cause, won a couple of Finnish hip-hop championships, released vinyl records and other stuff on Fjuu Records and so on. They have also been touring with, for example, Kemmuru, Ruudolf and Super Janne. First bits of their debut album were heard on "Mestarisoundi Soundcheck 2007" compilation, which featured the highly praised track Pojast miehex, featuring Ruudolf and Aksim on the vocals.
