Just read the Herald obit. Apparently Martyn Bennett worked closely with Huun Huur Tu, who happen to be the other gig (besides his mother's) that I went to at Celtic Connections last month. And apparently, he first connected with them back in Edinburgh when they played the 1997 Festival there. I saw that gig and had one of the most mind-blowing nights of my life. My father died in a hospice in New Zealand as my reality was being altered by the throat singers.
Thanks to Mhairead for mentioning the Herald obit.
