The band was formed in 1996 and originally, it was unnamed. In 1997, the band had to come up with a name before performing at North Beach, Durban, and came up with "Tree". They added the "63" part of their name in 2000 due to a naming conflict with an American band. 63 had been the name of their second album, which was named in reference to Psalm 63.
'We were originally just "Tree", after the numerous references in the Bible to trees: the garden of Eden, the cross Jesus hung on etc. "63" was the title of our second record, and it came from Psalm 63. When we got to the States in 2000, we discovered a band in Boston called "Tree" already, and they were unwilling to give up their band name, so we had to either alter or change ours. The compromise was "Tree63".'—John Ellis, Interview with Christian Music Daily
Tree63's recording of Matt Redman's "Blessed Be Your Name" helped to spark the song's popularity. This recording was featured on the 2005 edition of WOW Hits and was nominated for two Dove Awards. On a February 2, 2007 broadcast of 20, The Countdown Magazine (special edition, Praise and Worship), guest Chris Tomlin described Tree63's rendition of "Blessed Be Your Name" as "...the definitive recording of one of the most all-encompassing songs in the entire world of Christian music." The song was then announced as the number 3 Praise and Worship song of all time.
Tree63 parted ways in 2009, and John Ellis returned to South Africa, where he started his solo career. His debut solo album, Come Out Fighting, was released in June 2010.
On November of 2014, Tree63 released previously unreleased songs from 2006. They claimed that the tracks were considered candidates for their Sunday! album.
