The Crida is the opening ceremony of Fallas. Here is a good video of the one hour program. There are lots of nice light effects on the towers. The impressive although very short fire boomies start around 50′. You can skip forward wherever you like, especially if you want to avoid the speeches in Valenciano. There is lots of pop music as well as some traditional Valencian folk music.
It was a pleasant evening under the clear night skies.
