Changes

Petra is one of the founders of Christian Rock music. The name Petra is from the Greek language meaning 'rock'. The band was founded by guitarists and songwriters Bob Hartman and Greg Hough in 1972, while they were studying at the Christian Training Center in Fort Wayne, Indiana. At first, they shared singing duties until they added vocalist Greg X. Volz to their lineup around 1977. Over the years, they have gone through many lineup changes. Hartman is the only member to play on all of the albums. However, he did quit touring with the band for awhile during the late 90's. Volz left the band in 1985 to pursue a solo career. In 1986, former Head East vocalist John Schlitt joined the band, bringing on a more hard rock/heavy metal-type sound.

Recently, Hartman announced that Petra will retire at the end of 2005, after 33 years of ministry.
