NOFX was an American punk rock band, formed in Los Angeles in 1983. Bassist/lead vocalist Fat Mike, rhythm guitarist Eric Melvin and drummer Erik Sandin were original founding and longest-serving members of the band, who have appeared on every release by the band, although Sandin had departed briefly in 1985, only to rejoin the following year. El Hefe joined the band in 1991 to play lead guitar and trumpet, rounding out the best-known iteration of the lineup.
