Can you find a reproduction of the actual recording sent out on one of those "Pioneer" spacecrafts of Bach's 3rd Brandenburg concerto?
I want to know what will be heard by ET in a zillion years.

I think you will find that it was the Voyager spacecraft which carried the music. The Pioneer spacecraft just carried an image.
This is from the NASA web site.
"As the first two spacecraft to leave our planetary solar system (in 1983 and 1990, respectively) Pioneer 10 & 11 carry a graphic message in the form of a 6- by 9-inch gold anodized plaque bolted to the spacecraft's main frame."
Voyager carried what became known as the Golden Record. This included a recording of "Bach, Brandenburg Concerto No. 2 in F. First Movement, Munich Bach Orchestra, Karl Richter, conductor. 4:4." Not No.3 as you thought.
A similar question to yours appears on the NASA website this is an edited version of their answer.
"There was a book and CDROM published by Warner New Media in 1992. The book was a reprint of the Carl Sagan, et al, "Murmurs of Earth" that was originally published in 1978.
Carl Sagan and his colleagues did the assemblage of the information on the Voyager Golden Phonograph Record. Most of the material they used was copyrighted by the creators/owners and Sagan had to get copyright releases in order to assemble the original record. Subsequently, Warner Multimedia was able to obtain copyright releases for the 1992 version of "Murmurs of Earth", by Carl Sagan, et al and included all the sounds and songs on the CDROM set that accompanied the Warner New Media release of the book. We have included on the Voyager web site (voyager.jpl.nasa.gov) only that information for which we were able to get release, that's why everything, especially the music and the photos, is not there.
Unfortunately, the book and CDROM are no longer being published and are hard to find as a set. Your best bet to find one quickly may be in a public or university library or at a used bookstore."
I have found that someone has placed the No.2 Concerto from this Warner record on YouTube.
I am satisfied that it is genuine as the poster, xlovenuggetx, has used the image from the CD disc on some of the other tracks. You can see the image on this page. You can find others by using the search term> "murmurs of earth" ( . Use the bracket as it narrows down the results and picks up xlovenuggetx's use of identifying the track number in brackets.
The poster has used some of the images to accompany the music, but if you wish to see all the images and hear all the sounds, they are on this website.
I believe that the original recording may have been re-released on this Deutsche Grammophon record. The review notes state that the cycle of recordings started in 1967 with Concerto No 1. This would tie in with the dates of the Voyager missions.

I hope this answer your question. If it does not, do ask for a clarification.
