Selection Thirteen… Postal workers canceling stamps at the University of Ghana Post Office… This is easily one of the most beautiful work songs I have ever heard. Its basically four postal workers whistling along to polyrhythmic stamping that I assume is produced using the tools of their trade. The track comes from a book/CD-ROM called Worlds of Music: An Introduction to the Music of the World's Peoples, which can be purchased through Amazon. It was featured (once again) on the WFMU blog (link to entry).
