Theirs was a mighty sound, but they were amplified by a small forest of microphones, and still had a hard time breaking through the synthesizer and rhythm sections at times! It was mainly banal Evangelical praise songs (You are mighty, Jesus is My Friend, etc.), except for one electrifying top-tempo gospel-style Glory Halleluia! Each song repeated often, ascending in volume, modulating chromatically upward and upward, plucking audience members one by one from their seats, their hands upraised or outstretched. Overpowering though it also is, the experience of this music speaks to people through people.
I was reminded of the international chorus assembled at Engage, the GLBTQ Asian conference I attended in Hong Kong (third picture down here), which drew from similar choirs singing similar praise music in Singapore, Taiwan, Hong Kong, and providing a different but no less moving witness.
