The band kept much of their sound from Invincible on their next album Alien Youth.
With little time between touring and recording, Skillet released Alien Youth on August 28, 2001, which was the first album that John Cooper took on production duties.
Skillet is an American Christian rock band formed in Memphis, Tennessee in 1996.
After Trey Mc Clurkin joined the band as a temporary drummer.
Skillet was only together for a month when they received interest from major Christian record label Fore Front Records. It was well-received, and the trio continued to write new material as they toured the United States.
Before the release of Alien Youth, Haaland left the band, and Ben Kasica took over on guitar.
The first single, the title track, was a major hit in the Christian market and drove Skillet into their first headlining shows.
Korey Cooper joined the band permanently and played keyboards for the recording of Invincible.
Because of this change, the musical style on Invincible changed to a more electronic sound.
A remix on "Monster" was featured on one of their popular podcasts.
The song "Hero" was used in the publicizing of the first football game of the 2009 NFL season between the Pittsburgh Steelers and Tennessee Titans, and the song "Monster" was used in the episode "Jason: The Pretty-Boy Bully" on MTV's Bully Beatdown.
Soon after the release of Invincible in early 2000, Trey Mc Clurkin parted ways with Skillet, and Lori Peters filled the drummer's position.
The band released their first worship album, and fourth album overall, Ardent Worship in late 2000.
The two bands met through touring together, but those bands disbanded soon after, so John and Ken's pastor encouraged them to form their own band as a side-project.
