Skillet was formed in Memphis, Tennessee in the mid-90s, with their first self-titled released through Forefront Records in 1996. The band's line-up remained the same until their third album 'Invincible', when John's wife Korey joined to play keyboards. Lori Peters joined on drums soon after the album's release. A third line-up change would happen after their fourth album, when Ben Kasica took over playing guitars. In late 2007, Lori Peters left and Jen Ledger took over on drums. In April 2011, Ben Kasica played his last shows and by April 16, Seth Morrison joined as lead guitarist.
The band's most dedicated fans are refered to as 'Panheads', and have been known to turn up to concerts with skillets, banners, writing on their cars, and so forth.
