Spear is one of my favorite audio editing programs in the world. It is a spectral analysis tool... it analyzes a sound and outputs it graphically, all frequencies/waves divided into separate partials. In layman's terms, whatever sound you import into Spear ends up looking like a bunch of squiggly lines which you can then edit. You can take out a singular frequency or a whole range by deleting various squiggly lines. I absolutely adore the software. If you are any level of audiophile, I suggest you download it immediately.
In any case, today's experimental piece is brought to you by Michael Klingbeil's Spear, Pro Tools, and the most beautiful Primary song ever written.
