According to the band's blog, Brad Avery is leaving Third Day. To quote the site:
"Third Day and Brad Avery have made the very difficult decision to part ways.
We appreciate Brad’s many contributions to the band's career to date, including his work on our forthcoming album, but the time has come for us to follow our separate paths.
He has been an important part of Third Day for the last 13 years as we've traveled the world together and performed over 1,000 concerts. We will miss him as a band member but he will always remain our brother and our friend. Brad is a wonderful person, gifted songwriter and talented musician. We trust that God has amazing plans for his future."
