Bob Hartman formed Petra (along with original members Greg Hough, bassist John DeGroff and Bill Glover) in 1972 while attending a Christian college in Fort Wayne, Indiana. By the next year, the band was a regional sensation and in 1974 Word’s then-new contemporary label Myrrh released its first album. Though some Christian bookstores refused to carry it, young believers demanded it, as they would for many years to come. Nearly 30 years later, Petra is still Christian music’s top-selling band with both Dove and Grammy awards to add to their legacy.
