On Sunday March 18th 2007, the congregation of Hillsong Church gathered together as ONE in Sydney's largest indoor stadium, "Acer Arena", to unite in ONE sound and record this album. The atmosphere was electric, as the sound of over 13,000 worshippers reverberated throughout the auditorium - real people living real lives - singing, dancing and giving expression to the faithfulness of their God through wholehearted worship, led by Darlene Zschech and the Hillsong worship team.
