Sardonyx was a power metal ministry band and did live shows from 1990 to 1994. It was founded in 1988 by Rod Feltman, Tim Swarthout, Chuck Turner, Michael Anthony Simione and Tom Denlinger. After releasing a demo in 1990, entitled 'Rebel Of Reason', their one and only full-length album, 'Majestic Serenity', saw the light of day in 1992. This was released on the bands own label, Lightshine, which later on also became the bands ministry foundation. As a band, Sardonyx broke up in 1994. But in 2002 the band was once again announcing activity, and in 2005 a brand new EP was released. 2007 saw their album, and demo, reissued through Retroactive Records.
