Kisschasy are an Australian rock band that formed in Melbourne, Victoria in 2002. Their line-up consists of lead vocalist Darren Cordeux, bassist Joel Vanderuit, guitarist Sean Thomas and drummer Karl Ammitzboll. The band released two gold certified studio albums, two extended plays, a documentary DVD and a compilation album in their initial 10-year career, selling in excess of 90,000 records.

Kisschasy formed in 2002. Three of the four members of the band grew up near the small country town of Balnarring in the Mornington Peninsula of Victoria. Darren Cordeux, the lead singer and guitarist, grew up in Cranbourne, Victoria, a large town north of the Mornington Peninsula, Victoria. Joel Vanderuit, Sean Thomas and Karl Ammitzboll played in a local band called Tenpin, who achieved a little local success. The formation of Kisschasy happened when Tenpin met Cordeux's band at the Arthouse in Melbourne in early 2002. The band name ended up being a "toss-up between Kisschasy and "Other Stuff".

In 2004, Kisschasy released two EPs on indie label Below Par Records, the first titled Darkside / Stay Awake, the second Cara Sposa. The band toured in support of these EP's right up to the point of recording their first album United Paper People.

Kisschasy's debut album United Paper People was recorded and produced by Phillip McKellar (Silverchair, Grinspoon) in Sydney during February 2005. The band then flew to Seattle in March of the same year to mix United Paper People with Barrett Jones who had worked with the likes of Nirvana and the Foo Fighters.

The first single from the album was "Do-Do's & Whoa-Oh's", which gained heavy rotation on both commercial and alternative radio. The band received an ARIA Award for Breakthrough Artist - Single at the ARIA Music Awards of 2005 nomination for "Do-Do's & Whoa-Oh's", as well as a Channel V Oz Artist of the Year nomination in 2005. Kisschasy were also nominated for the "Spankin' New Aussie Artist" award at the MTV Australia Video Music Awards 2006.

In late 2006, Kisschasy went into pre-production for their follow up to United Paper People, titled Hymns for the Nonbeliever. They recruited British producer Chris Sheldon, who had previously worked with acts such as Feeder, Pixies, Biffy Clyro, Therapy?, Anthrax and Foo Fighters, to produce, engineer, and mix. The album was recorded at The Grove Studios in the Central Coast of NSW and Rockinghorse Studios just outside Byron Bay throughout December 2006 and January 2007. The album's first two singles, "Opinions Won't Keep You Warm at Night" and "Spray on Pants", were mixed by Jerry Finn.

Hymns for the Nonbeliever was released on 21 July 2007. Hymns for the Nonbeliever was Kisschasy's second album to be certified gold in Australia. The third single off the album was "Strings and Drums".

In May 2008, EMI released a 16 track Kisschasy compilation album, titled Too B or Not Too B. The album includes acoustic tracks and b-sides, with a bonus DVD of all their music videos from United Paper People and Hymns for the Nonbeliever (excluding "Ugly Birds in a Beautiful Cage" as it was released just after the DVD).
