Alien Youth is the fifth album released by the Christian rock band Skillet. Developing their sound into hard-hitting industrial rock, it was released August 28, 2001 through Ardent Records. This was the first Skillet album to include guitaristBen Kasica, replacing Kevin Haaland. Kasica joined Skillet late in the recording proceess for the album, only recording guitars on "Earth Invasion". It peaked at No. 141 on the Billboard 200 and No. 16 on The Australian Christian Albums Chart.
The video for "Alien Youth" features the band in a futuristic city, wearing futuristic clothes much like those seen in the "Best Kept Secret" video. The opening shot is something coming down to earth. It then cuts to the futuristic city, circling around a tower with large screens at the top that display the album cover. The band is mostly shown playing in the middle of the city, with various shots of the individual band members being shown on large television screens. The video was shot on a green screen.
Alien Youth: The Unplugged Invasion was Skillet's first DVD, released in 2002 by Ardent Records. They perform four songs from Alien Youth and one from Invincible as a mini acoustic concert. All of the instruments are unplugged (besides the keyboards) in place of acoustic guitar and softer drums. In addition, it includes the "Best Kept Secret" music video, a Bible Study from John Cooper, and a photo gallery of the unplugged performance.
