In 1983, Metallica released their first studio album "Kill 'Em All", on which few of the songs were still credited to Mustaine. One year later, Metallica released their second studio album "Ride the Lightning". "Ride the Lightning" and "The Call of Ktulu," the album's final track, were the band's last songs to give Dave Mustaine writing credits. Metallica was one of few bands at the time to deviate from the then popular hair/glam metal trend that was taking place during the 1980s, led by bands like Poison and Mötley Crüe.
