Aaron Abeyta, known as El Hefe or simply Hefe, from el jefe (Spanish for "the boss"), is the most recent member of the legendary and seminal California punk band NOFX. Given this name by his fellow band members for his superior mastery of the insturments he plays, Hefe plays lead guitar, and provides trumpet parts whenever they are necessary. It has also been said that he was given the moniker because there were already two "Erics" in the band, and that an "Aaron" would just be too much.
