The Exploratorium is in San Francisco's Palace of the Fine Arts, and contains science, art, and human perception exhibits. It has long promoted museums, including its own, as informal learning centers. The 40th anniversary of the Exploratorium is, in part, being honored with monthly podcasts of the radio series Speaking of Music, that ran from 1983-1992. Prominent musicians were interviewed in front of a live audience, and some of the musicians even played some music on the show. The podcasts are called Speaking of Music Rewind and a new one will come out monthly until November 2010. The website has "Upcoming", "Recent", and "Featured" sections of podcasts from which to choose. Some of the prominent artists that were guests on the show include, Brian Eno, Phillip Glass, and Laurie Anderson. These podcasts can be found in the "Recent" section.
