passes #1 as "the subject of multiple, non-trivial, published works appearing in sources that are reliable, not self-published, and are independent of the musician or ensemble itself." Based on the source descriptions of pre-1990 activity for this group as being mostly small and private, there probably isn't much available press coverage from the first ninety years of their existence. But since 1990 or so they have been covered multiple times in multiple RS outlets by multiple writers over several years, which seems to meet the requirements of #1
