Invincible is the third full-length album by Christian rock group Skillet. It was released in 2000 from ForeFront Records and Ardent Records. This album continues the electronic rock that was heard on their previous release but marks the exit of original guitarist, Ken Steorts, and the entrance of his replacement, Kevin Haaland on guitar, as well as John Cooper's wife Korey on keyboards, loops, sampling and programming.
There was a music video made for the song "Best Kept Secret". It was the first video by the band to have a story of some kind in it, though the story is very brief. Some of the video shows the band in the story portion in futuristic clothing, while the rest of it shows them playing in a room in similar clothing. The story portion shows the band entering a hallway, which they walk along until they come to a massive room where prisoners are being held in glass cells. All of the prisoners appear to be asleep, with gas masks over their faces. Each band member takes a pipe, at which point all of the prisoners wake up, and the band then smashes the glass of the cells. All of the prisoners fall out of the cells and onto the floor. The band helps them all up as they remove their masks. After freeing the prisoners, the band exits the way they came in.
