This year has seemed unusually strange and often tragic to me, as to many of the people I know and talk with on a regular basis. One factor, of course, is the insane American political campaigns and outcomes, and the implications for all of us, all over the world, for our planet itself, and for all Earthly creatures everywhere. Another factor has been the large number of famous and beloved musicians who passed away this year. Of course, many millions of people, of all kinds, died this year—an estimated 58+ million individuals, — and with a few days left till the end of the year, many more people, hundreds of thousands, will be added to this number. No way of knowing how many musicians, even famous musicians, will be among them. But the number of famous musicians who have departed this year has been startling somehow and, of course, saddening. I’m not entirely sure why, of all the various kinds of beloved and publicly celebrated persons who have died this year, so many of us have felt so impacted by the passing of many or “our” musical “stars”, but so it is.
I’ve listed below some names of various departed musicians (and some persons publicly involved in music), whom I feel are likely to be familiar to a majority of my American readers. The notes come from lists on wikipedia; I’ve combined and reduced the entries found there to form this personalized, highly selective list. If you think of other departed musicians who are on your own list, let me know. Of course I’ve left dozens of names off this particular listing.
It happens that I personally knew, somewhat, more than one or two of the persons named here, but only on a more or less superficial or casual basis. There are a few more whom I had simply met only once or twice in a mostly conventional manner. In some additional cases I have felt somewhat privately “connected” simply through sharing personal friends and/or friends-of-a-friend, without ever having known the musicians directly. But I wasn’t particularly close to any of these talented persons. Much as I love a lot of the music, I can’t I say I was among the most intense super-big-fans of any of the great stars who have departed this year. So I haven’t been quite so deeply devastated by their deaths, not like so many of their serious fans (and of course their family and friends!) have been. Still, just like everyone else, I certainly feel their loss. I really love so much of the music left to us by these amazingly talented individuals, and where it applies, of course have really enjoyed being personally acquainted, howsoever slightly, with a few of them. Some of my friends are pretty big fans of these stars, and I feel most sorry for them. It has been kind of startling at times to learn of the passing of all these artists, so many of whom have been such a part of our lives over the years through the magic of their music.
