MxPx is a punk/rock band that formed in 1992 in Bremerton, Washington, United States.
MxPx started as three 15-year-old kids calling themselves Magnified Plaid pounding out music inspired by and similar to the The Descendents and other Southern California pop-punk bands. They didn't really love their band name, however, which was a tribute to the original guitarist's penchant for wearing one particularly loud plaid shirt.
