Having recently gotten back into CDs in a major way, I stumbled across this series of videos on YouTube and was captivated.
While even back in the day I had a general understanding of how this stuff worked, to this day it amazes me how any of this actually manages to work (and I've been a technophile my entire life). Forget the technobabble. It's voodoo and black magic, I say. Voodoo and black magic!
