A field recording made of Ghana post workers canceling mail.  The rhythmic sounds are a combination of the following:

• Light Thud - Slapping of the letter to bring in position on the table to be canceled.
• Lowest Thud - The stamp being inked one or more times.
• High Thud – The letter being stamped and canceled.
• A High Pitch Snap -  Scissors being snapped together for rhythmic effect
• Hand Clap – Done by the whistler

There are four men in this recording, two doing the stamping, one man handling the scissors and one man who carries the tune and hand claps.

Absolutely breathtaking.
