How much singing on other NSB projects?

I’m new to the group and I just finished The Winter Ray. I really liked it and especially the contrast between the drones and ambient parts with the singing on songs like “Bloody Snow”, which I thought was the most beautiful part of the album. I’m just wondering if there is more conventional vocals on any other albums by them? I know it’s mostly ambient but I enjoy the switch up.

Don’t spoil where it appears but id like to know if it does and if it does so much or little.
