(SEIZURE WARNING!) Glitch-speriment: Bass^2

I was bored and frustrated because a thunderstorm nearly wiped out my TV/satellite receiver, so I spent a good while updating that bass gif I made awhile back, making it bassier and giffier and other nonsense words. I noticed I could decrease the level of bass to -15 the same way I could increase it to positive 15, so I effectively doubled the amount of images I had for an animated gif.

Glitching done in Audacity, animating done in GIMP.
