Reel Big Fish is an American ska punk band from Huntington Beach, California. The band gained mainstream recognition in the mid-to-late 1990s during the third wave of ska with the release of the gold-certified album Turn the Radio Off. Soon after, the band lost mainstream recognition but gained an underground cult following. As of 2006, the band was no longer signed to a major record label and has since been independent. After numerous line-up changes, frontman Aaron Barrett is the last remaining founding member still performing in the band.

Ska is a music genre that originated in Jamaica in the late 1950s and was the precursor to rocksteady and reggae. It combined elements of Caribbean mento and calypso with American jazz and rhythm and blues. Ska is characterized by a walking bass line accented with rhythms on the off beat. It was developed in Jamaica in the 1960s when Stranger Cole, Prince Buster, Clement "Coxsone" Dodd, and Duke Reid formed sound systems to play American rhythm and blues and then began recording their own songs. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British mods and with many skinheads.
