Early morning collection of rubbish by the binmen. You can hear the truck moving slowly down the street and the men wheeling the bins around as well as the bins being tipped into the back of the truck.
Nottingham royal concert hall. Balloon burst at front of stage and recorded from the front of house mixing position. Might sound good for orchestras but rubbish for rock bands. .
I dropped a roll of toilet paper inside a small bathroom trashcan about 30cm away from the mic. This was recorded at the open window institute sound booth in centurion, south africa.
