due to the band becoming more popular they signed to a record label named elektra. however, joey belladonna was fired from anthrax in 1992 and was replaced with john bush, who was in a band called armored saint that had recently broke up. the band's first album with this singer, called "sound of white noise", was also successful, and was dark like "persistence of time", but also sounded a little bit like the grunge bands that were popular in the early 90s.
