Galloway's talk is excellent, probably the best so far I've heard on Laruelle. It actually serves the dual purpose of not only covering that specific essay, but also introduces Laruelle's "non-philosophy" quite nicely. I have to admit that I'm a beginner when it comes to Laruelle and am still trying to figure out some of the basics. Galloway's talk was immensely helpful.
