Part of a firework display. Can hear roman candles with screamer units, and the launch and burst of shells. You may wish to turn up the bass and wear headphones! now geotagged at last - thanks for all the comments!.
This is part of a commercial summer firework display in the uk. There are bombette candles, crackle candles, tourbillion units and shells of various calibre, some of which contain crackling material. Analogue recording.
