Hello,
I did a little research on Tree63 and what I learned from "Beliefnet" (a Christian media website which was founded by Steven Waldman and Robert Nylen) is that "after 10 years together, the Christian rock worship group Tree63 is stepping away from the stage to get on with their lives". This was confirmed by lead vocalist, John Ellis.
"We haven't broken up, but we are at a stage where we need a sabbatical and to become other things," Ellis told Tonight.co.za. He says the group's other two members, Darryl Swart and Daniel Ornellas, are still in the States and working on projects that are not musical." This quote was dated September 18, 2008.
I've also learned from John Ellis' site that he has "launched his solo career in 2010 after more than a decade of international success. His debut solo album, Come Out Fighting, was released in June 2010"
I hope this answers your question.
Blessings,
Snowrose
