A recording over five years in the making, it’s worth leaning on what a technical accomplishment this is.
Dispersed volunteers around the world, most of whom have not met each other, have spent five years making a recording which has recently been released. This includes a number of people who have sung chorus parts whose individual recordings in various parts of the world have been skilfully merged into one MP3.
You can download the recording for free.
I’m credited as being in the chorus, although I don’t actually remember making any recordings of this!
