Rock then reunited with friend Chris Impellitteri and recorded the self-titled debut EP of the latter's band Impellitteri. However, he was also committed to another band named Joshua, so he could not continue with the band at the time. Rock recorded one album with Joshua, which was characterized by the editor of HM Magazine as being "probably the best melodic metal album in the universe." He also worked on other projects (Dennis Cameron's Angelica, Driver) which gave him knowledge of international musicians that would serve him well later.
In the early 1990s, he received a call from Chris Impellitteri to once again join his band. He agreed and became the band's lead singer until 2000. Together, Impellitteri released five successful albums.
In 2000, Rock decided to pursue his own solo career and parted ways with Impellitteri amicably. That same year, he released his first solo album called Rage of Creation. The album received critical praise and Rock has gone on, releasing three more albums (Eyes of Eternity, Holy Hell, Garden of Chaos).
In May 2008 it was announced that Rock reunited once more with Impellitteri. Their new album, Wicked Maiden, was released in April 2009.
Rock has one son, Alexander John, with his wife Liza. Alexander was born January 5, 2006. Rock is a born again Christian, which has formed the subject matter of many of his lyrics.
