Released on this day in 1979, Dynasty is the seventh studio album by KISS. It was the first time that the four original members did not all appear together for the entire album. Peter Criss was hindered by injuries to his hands that he had suffered in a 1978 car accident, and was subsequently replaced by studio drummer Anton Fig. The album features the hit song "I Was Made for Lovin' You" which draws heavily from the disco style that was popular in late-1970s. According to legend, the members of the band were in conflict with their producers, who wanted the band to shift to a more commercial sound. In response, the band argued that lucrative disco songs could be written by anyone in a short time frame. The story goes that the song's demo was completed in mere hours after the bet. While the story is unproven, Paul Stanley, who co-wrote the song with Desmond Child and Vini Poncia, has stated that it was a conscious effort on his part to prove how easy it was to write and record a hit disco song. It would prove successful as it was the band's second Gold single, selling over 1 million copies, and helping the album sell more than 1 million copies as well.
