Rivers Cuomo (; born June 13, 1970) is an American musician best known as the lead vocalist, guitarist, and songwriter of the rock band Weezer.
Raised in an ashram in Connecticut, Cuomo moved to Los Angeles at 18, where he played in several rock bands before founding Weezer in 1992. Burnt out after the success of Weezer’s self-titled debut album, Cuomo enrolled at Harvard University, but dropped out to record Weezer’s second album, Pinkerton (1996); he later re-enrolled and graduated in 2008. Though Pinkerton was later frequently cited among the best albums of the 1990s, it was initially a commercial and critical failure, pushing Cuomo’s songwriting toward pop music. However in the years since its release, it has been certified platinum and is widely viewed as one of the best albums of the 1990s.
Cuomo has also released three compilation albums of home demos: Alone: The Home Recordings of Rivers Cuomo (2007), Alone II: The Home Recordings of Rivers Cuomo (2008) and Alone III: The Pinkerton Years (2011). He has collaborated with a number of artists; in 2013, he and Scott Murphy released a self-titled Japanese-language album under the name Scott & Rivers.
