During its 33-year career, Petra influenced countless artists in and out of the Christian scene. Petra was the only Christian band to play at the 1992 Farm Aid concert and the first Christian band to be included in the Hard Rock Cafe. In 2000, Petra was the first Christian rock band to be inducted to the Gospel Music Hall of Fame. "The doubts about popular music mixing with Christian lyrics have mostly vanished due to their 25-year track record of proven ministry and changed lives. Petra was a true pioneer for our industry," GMA President Frank Breeden said at the time.
