Silicon Red is the greatest folk singer in the Universe Gamma. He is introduced to the series as he is being released from 11-Worth Variable Security Prison. He is apparently one of a class of "mineral" aliens akin to the Borax Kid. He plays a guitar he named Salmonella, which he "...met doing hard time on a Mississippi chain gang..." in spite of the fact that he has only two fingers and a thumb on each hand (which is only one finger less than most of the inhabitants of the Futurama multiverse.)
