You have to supply your own audio, but may I recommend this?
Over the holiday weekend, the Inquirer did a piece on the city’s Department of Records’ Youtube channel. The channel, seen here, is a time capsule of sorts featuring videos produced for various city departments from around 1955 to 1981. There’s the Ed McMahon narrated Philadelphia Tomorrow City – Today, an urban renewal film from 1955, and the unfortunately silent footage of some Vet construction above. You could probably lose a few hours watching all this stuff.
There’s also this video of aerial shots of the city when William Penn still stood above it all, which I bet also works well with the music suggested above.
