The duo's first full-length studio album, "Matt & Kim", was released in October 2006 on the IHEARTCOMIX record label. The album received generally mixed to positive reviews. Adam Moerder of Pitchfork referred to the duo as the "quintessential 'party' band" in a review of their self-titled debut album. Matt and Kim also gained significant publicity for their music videos. The video for "Yea Yeah," which depicts the pair being hit with food from their refrigerator, has been considered one of the initial catalysts for their rise in popularity. They played the Lollapalooza festival in August 2007 and also played the Siren Music Festival earlier that year.
