A third John Boswell composition on science has now appeared at symphony of science. It's a bit slower and moodier that the first two efforts I featured. All three are on the link you get clicking the title here. And it has also been announced that a collaboration with the great Jack White and friends at Third Man Records, in Nashville, TN led to release of a 7" vinyl single of the song "A Glorious Dawn," featuring a special etching of the Voyager Golden Record cover on the B-side. This makes for a great collector's item, and a novel way to experience the song as well. It was released 11/9, on Sagan's 75th birthday.
Ann Druyan and Jack White apparently collaborated on this so we can now breath a sigh of relief that there will not be legal problems concerning these remixes of Cosmos and other materials. You can go to the Third Man Records site to learn more about the release: http://www.thirdmanrecords.com/news.html
