The banner image, Yes Music in the Amphitheatre, 1970, is a photo taken in 1970 by Ed Uthman, available via Creative Commons Licence.
Ed says about the photo:
This was one of the first photos I shot on campus, and it remains my favorite. I have a poster print of it hanging on the wall at home.
The record he’s listening to is Yes’ self-titled debut album from 1969, a couple of years before Yes had its first big hit, “Roundabout.” I myself did not become a Yes fan until 1975, when my med school roommate, Tom Grabenstein, played the cassette tape in his VW Beetle during a vacation trip we took to to Black Mesa State Park in far west Oklahoma. Since then, I have been a rabid fan of the group in its many incarnations.
In 2010, this photo was used in the onstage video that accompanied the performance of the song “Jazz Man” by Carole King in her “Troubadour Reunion” tour with James Taylor. Even though the photo was in the Creative Commons, the production team courteously asked me for permission to use it, which of course I enthusiastically agreed to.
