Zschech is arguably the single most well known and successful contemporary worship leader, much to the thanks of her record-breaking praise song "Shout to the Lord." It's been recorded on 20 albums and sung by an estimated 25 million churchgoers every week. She reaches several million more first hand, leading worship for televised services broadcast in 125 countries worldwide. Her ministry as Worship Pastor at Hillsong Church, one of the largest churches in Sydney, Australia, gives her a platform to "reach the nations" with her growing list of published praise songs and inimitable heart and soul.
