I can't speak for Will E, but it just so happens I have been wrapped up in Myanmar (Burma) worship music for some time now. It started about 4-5 years ago with Myanmar choir music going viral on You Tube. My guess is that it was a little too upbeat for the authorities. Whatever, the videos were taken down. Now, they are back in a different form, the members now adults. In the meanwhile, there has been another military junta, basically not unusual in Burma.
This request might not be as hard to fill as we might think. What they are doing appears to be a fusion of 1950's country music with contemporary Praise & Worship.
Search You Tube for "EBC Central Choir," "The Seraphim Choir," and "The Myanmar Choir."
Another fruitful genre is the solo vocalists. Somewhere in between is Akuk. She is popular with locals and visitors and could be called "the old hand" at it.
