Every new year's eve, my city of Grand Forks, North Dakota, holds a modest festival to ring in the new year. It's capped with a fireworks demonstration at the stroke of midnight, which is usually successful in bringing out the stout folks to brave the cold and watch some big booms!
Here's a bit of soundseeing of the 2009 demo for your listening pleasure.
(Recorded with a Cowon iAudio U3 and its internal condenser mic. The audio has about a 30 dB wide dynamic range to preserve the effect of the loud bangs relative to quieter speech and background sounds. Therefore it may be hard to make out the background in noisy listening environments.)
