Hillsong United, a constantly evolving group of musicians affiliated with the youth ministry efforts of Australia’s Hillsong Church, are one of the most important acts in contemporary Christian music. With all four of their studio albums landing at No. 1 on the U.S. Billboard Christian Albums chart, it’s clear that Hillsong’s uplifting, thoughtful worship songs appeal to a new generation of listeners seeking spirituality through music. The international success of the group belies its grassroots beginnings – Hillside members began recording their original compositions in 1998, releasing self-produced albums every year until the 2007 release of their first studio album All of the Above, which peaked at No. 1 on the Christian Albums chart. Their next three albums would all achieve the same success, including 2013’s Zion, which includes the breathtaking nine-minute “Oceans (Where Feet May Fall),” Ticket buyer are impressed by the band’s delicate, spacious arrangements and continue to praise their inspirational live concerts on 2013’s Welcome Zion Tour.
