Honestly all these tracks come very close because I'd give nearly all of them a perfect 10.
You can really hear The Mars Volta put their heart and soul into this album, which is dedicated to their close friend Julio Venegas who committed suicide. That's also the concept of this album, and everything from the vocals to the instruments describe that theme extremely well
