I hope I am not stepping into something political here. I simply want to point out there is a bit more information available than just the sound files for the material on SoundCloud for which Peter Laban provided a link above.

I looked at the web page of The Song Collectors Collective (here) and found that there is some information (perhaps not as much as would be wished) about the singers, including some of their own words. The amount of information varies, so if one looks scant, don't assume all are equally so.

You get to it by clicking on 'TRADITION BEARERS' at the top. This takes you to a page with an image and a bit of text about each person, and if you click on one of these you get to a page with information about them along with the material they provided. In some cases there is more than one link to (what I assume to be) the same sound file, and for me sometimes one would work and another not, so don't give up at the first failure.

As for the collectors, the 'SCC TEAM' is listed under 'ABOUT' (at the top). I have not explored deeply enough to know whether 'the team' means all the collectors represented on the site or a subset who have overall responsibility. To learn more about these individuals, however, it appears one has to go back to one's search engin of choice to see what might be available on the Internet about them.
