I showed excerpts from this video in my workshops. This one video has two different things in it.
Spatter cones and fissure eruption up to the first 1:30 of the movie.
After about 1:30, the rest of the movie is of an AA flow. I showed this portion in the workshop. Although there is wind noise, you can hear the sound of the glassy boulders as roll down the front of the advancing lava front.
