Open Heaven / River Wild (stylised as OPEN HEAVEN / River Wild) is the 24th live album of Hillsong Worship, which consists of several worship pastors from Australian church Hillsong Church. The album was recorded during the 2015 Hillsong Conference at the Allphones Arena from 29 June until 3 July 2015 and was released on 16 October 2015, under Hillsong Music, Sparrow Records and Capitol Christian Music Group; this marks the first time the church's annual worship album was recorded entirely during the conference, as opposed to the annual July releases that coincide with the event. Michael Guy Chislett oversaw production of the album, while Hillsong senior pastor Brian Houston and his son, worship leader Joel Houston, served as executive producers. Open Heaven / River Wild features several prominent vocalists of Hillsong, including Reuben Morgan, Joel Houston and Marty Sampson, as well as the Hillsong United band and the Hillsong Young & Free group. Following the Easter release of "O Praise the Name (Anástasis)", the album's lead single, "One Thing", was released on 18 September 2015.
