At 4 pm (hawaii time), it's the sounds of birdsongs and blowing light breezes in the trees lining the rather dry river near my home in honolulu. You can also hear the humming of my refrigerator in the background.
Taken at about midnight on a saturday night / sunday morning while waiting at a bus stop on indian canyon drive in palm springs, ca. I used a tascam dr-07mk2 recorder.
