I have been a fan of Aaron Ximm's quiet american for a long time. Close your eyes, put on your headphones, and be somewhere else thanks to his one minute vacations - field recordings submitted by people like you and me who take a microphone and tape machine along with them on their travels around town or around the world.
I finally worked up the nerve to send in one of my own, from my son's first fencing tourneyment earlier this year. It went up yesterday! Go to one minute vacations and have a listen!
