Rock Choir Live 2019. Plymouth. 600 Voices 4 Choir Leaders Live Band. What a wonderful musical experience this was for all concerned. This gave many of our members a unique opportunity to sing as part of a massed choir of 600 voices. It was stunning! Powerful, emotional, sensitive, musical... I could go on. Great Rock Choir experience. We also raised over £1000 for the Rock Choir charity Nordoff Robbins.
