Free Music Archive (FMA)
For the Dr. Glass Podcast, I've recently dabbled in the incorporation of music into the mix a bit more often. I'm being pretty turned on to a number of different means of music creation as well as sampling some royalty free loops and premix tunes.
One recent discovery that I'm VERY pleased with, is the Free Music Archive (FMA). This is an awesome resource with some hidden talents throughout. Granted, not all of this is something you'd listen to on your own, but one particular beat has caught my attention enough to be used in one of my latest videos.
