It’s fascinating to watch great artists evolve over long and prolific careers. But what of the artists who die young? When the greats don’t live long enough to see their 50th birthday, let alone their 40th or 30th, we all feel the loss. Whether it’s John Lennon, John Coltrane, Jeff Buckley or countless other talents who died prematurely, it’s not just their families and friends who mourn the loss, but the world.
