Five Iron Frenzy is an American band formed in Denver, Colorado, in 1995. Best known for playing ska punk music characterized by an offbeat sense of humor and prominent Christian themes, Five Iron was one of the pioneering figures of the Christian ska movement which emerged with ska's mainstream revival in the 1990s. Since 2000, the band's music has shifted away from straight ska to include and embrace stronger alternative rock and pop punk influences, though it continues to create ska music and feature Christian overtones despite several members' changes in religious beliefs.
