Youth Brigade is an American punk rock band formed in Hollywood, Los Angeles, California, United States, in 1980 by the brothers Mark, Adam, and Shawn Stern. The band subsequently founded BYO (Better Youth Organization). Many later punk bands cite Youth Brigade as an influence, including The Nation of Ulysses and The Briefs.
Youth Brigade has released five studio albums (counting one released as The Brigade), of which the last was released in 1996. Almost each album was recorded with the original lineup of the Stern brothers (Mark, Adam and Shawn); bassist Bob Gnarly replaced Adam in 1985 during the recording of The Dividing Line, which was released as The Brigade. Adam returned in 1991 (when the band reunited) and contributed to the band's 1992 EP Come Again and their next two albums (Happy Hour and To Sell the Truth) before leaving once again in 2007. Youth Brigade continues to tour to this day, although, other than six new tracks on the 1999 split album BYO Split Series Volume II, they have not released a full-length studio album since To Sell the Truth in 1996.
