2 Royalty-Free Audio Tracks for "Erdbeben"

Tried to create an earthquake-sound with sounds i have recorded with my zoom h5.

I've made a bassline. A deep one. After that my computer decided to do the opposite. He made it, with bugs. My asio driver has some troubles, but i like the glowing effect, it gives more insane'ness :). Triple osc, echo, phaser.
