Mindless Self Indulgence (often identified using the abbreviation MSI) is an American musical group formed in New York in 1997. Their music has a mixed style including rap, punk rock, alternative rock, electronica, techno and industrial. Due to the style of their music lacking a definite genre, they coined the term 'Industrial Jungle Pussy Punk' to describe their music, but later, they denounced the term. Their group name is derived from a solo album that frontman Jimmy Urine and his brother self-recorded in 1995. The group was formed when Urine was joined by fellow musicians guitarist Steve, second guitarist and brother Markus Euringer (soon to be replaced by bassist Vanessa Y.T, who was later replaced by LynZ), and drummer Kitty in 1997. They have released four albums, two EPs, one live album, and one live DVD. Rather than signing traditional record contracts, the band has licensed most of their albums to record labels, retaining ownership of the music. The group maintains a devout fanbase, and has opened for many well-known acts such as Linkin Park, My Chemical Romance, System of a Down, Korn, Sum 41, Insane Clown Posse and Rammstein. Notable bands who have opened for them include The Dresden Dolls, Rasputina, mc chris, The Birthday Massacre, Tub Ring and Dog Fashion Disco.
