Innerpartysystem is an American electronica/industrial rock band. The group consists of Patrick Nissley, Jared Piccone and Kris Barman. Explaining the origins of the band name, Piccone is quoted as saying: "In George Orwell's '1984' social classes were defined as the inner party, outer party, and the working class. It sounds really 'holier than thou' when you say it, we're really not this full of ourselves, but we liked the idea of creating this full, multimedia, over-stimulating, elitist environment that we were trying to invite everyone into. It's the ironic elitist class". The band is also well known for their live performance lighting largely by Andrew Nissley and unique videos directed by Stephen Penta.
Their debut EP The Download EP was released in November 2007 and their debut self-titled album in late September 2008. As of late 2008 the band started releasing seasonal mixtapes, new remixes including Ladyhawke's track Paris Is Burning and Katy Perry's Hot n Cold. In May 2009 the band digitally released the UK equivalent of The Download EP, entitled Heart of Fire. As of October 2009, the band are currently working towards their second full length album as well as an EP, with the album being released some time in 2011 and the EP early next year.
After rumours circulated the internet on Jesse Cronan leaving the band, it was confirmed on March 3, 2010 by a blog post by Cronan. Cronan stated that his reasons for leaving were because he felt "unsatisifed and unmotivated".
