La Mascletà, Falles / Spain, Valencia

La Mascletà
The Mascletà, an explosive barrage of coordinated firecracker and fireworks displays, takes place in each neighbourhood at 14:00 every day of the festival; the main event is the municipal Mascleta in the Plaça de l'Ajuntament where the pyrotechnicians compete for the honor of providing the final Mascleta of the fiestas (on March 19). At 14:00 the clock chimes and the Fallera Mayor (dressed in her fallera finery) will call from the balcony of the City Hall, Senyor pirotècnic, pot començar la mascletà! ("Mr. Pyrotechnic, you may commence the Mascletà!"), and the Mascletà begins.
Mascletà is almost unique to the Valencian Community, hugely popular with the Valencian people and found in very few other places in the world. Smaller neighbourhoods often hold their own mascletà for saint's days, weddings and other celebrations.

I just got back from Valencia Spain a moth ago I was there during Fallas it was so amazing and so crazy there. You could hear this from where ever you were int he city. The finally night of Fallas was so much fun. This Mascleta must have been one of the first ones because all the ones i heard lasted for 5 plus minutes
