There are three hard rock guitar tunes (I know of) that were inspired by each other, that were originally inspired by the 1886 eruption of Krakatoa; the single largest concussive event ever recorded by man, releasing more energy than all the nuclear explosions the world has ever seen combined.

The second, inspired by Uli, was Eddie Van Halens incredible debut piece "Eruption":
The final, inspired by both... and by his dickish wanting to outdo both (which in a technical sense he did, but artistically I don't think so) is Yngwie Malmsteens "Krakatau":
