The Prize Fighter Inferno is an acoustic/electronica project consisting entirely of recordings by Claudio Sanchez of Coheed and Cambria. Although many people think that it is just a side project, Claudio does not want it to be viewed as such. The first album, called "My Brother's Blood Machine" was released on October 31st, 2006 through indie label Equal Vision Records. When asked what his sound is most like, he responded, "a mix of Iron & Wine and Bjork."

The "story" of this album is told by Jesse as seen in other Coheed & Cambria albums. This story is however, not completely separate from the Coheed and Cambria universe and several characters from the Co&Ca universe are mentioned interchangeably. The albums title, My Brothers Blood Machine, is a reference to a type of machine that is used within the story that is capable of ripping peoples bodies apart in order to free their souls.
