This is a cover/reimagining of a Radiohead B-side called Gagging Order, from the 2004 EP "COM LAG (2plus2is5)". Most of the guitar is a straight cover of the original (with a few timing changes and an extended ending), but I reimagined the vocal melodies quite a bit, adding harmonies for multiple voices.

Gagging Order (by Radiohead): a reimagining

I like to make sad music with whatever instruments are at hand.  Sometimes I make happy music, but I like the sad music the best.  I like to experiment with tuning and temperament in order to express the greatest possible sadness.  A flat minor third is so bitterly unfulfilled, and I enjoy its flavor.
