"100,000 Years" is of "Kiss" the debut album by American rock band Kiss, released on February 18, 1974. Much of the material on the album was written by Gene Simmons and Paul Stanley, as members of their pre-Kiss band Wicked Lester. Simmons estimated that the entire process of recording and mixing took three weeks, while co-producer Richie Wise has stated it took just 13 days. "100,000 Years" begins with a bass riff by Simmons. The live version includes a long drum solo continuing on from the short one found on the album, as heard on Alive! The demo version can be heard on the 2001 release of the Kiss box set. There was a lost verse towards the end of the song which never made the final cut. "I spent a lot of time listening to and relearning a lot of the solos I used to do," remarked Frehley during the band's 1996 reunion. "Like the one in '100,000 Years' – I was listening to it before the tour started, thinking it was just about the nuttiest solo I'd ever heard. I'd never write something like that today."
