John’s eight-year stint with legendary rock band, Head East, put him on the map in terms of his career—the band was celebrated for its raw energy and swagger. John’s career seemed set, but it all came to a distressing end in 1980 when he was let go by the band. The reason: John had an out-of-control drug and alcohol addiction. In 1986, he joined Christian rock group, Petra bringing with him his amazing vocal range and abilities that made him a legend with Head East. Except this time, his mind was no longer blown on drugs, and alcohol-he was clean, focused, and armed with a powerful message: God made us too be winners-Jesus Christ is alive and through Him we are to be victorious in His perfect plan for us. Twenty years later and four Grammy awards on his shelf, sixteen Petra albums, and four solo albums recorded-millions of which have sold over the world-John is a man who lives for Jesus and makes no bones about his faith.
