John Boswell, the musician and producer of the wonderful Symphony of Science remixes, has created a new one, the fourth in the series: The Unbroken Thread. It features our man Carl Sagan, with David Attenborough and Jane Goodall. I like this one quite a bit.

I hope Boswell keeps making these. They’re very well done! The music is pleasant, the meaning is deep, and the words, of course, are beautiful and something everyone should hear.
