"My Heart Bleeds the Darkest Blood" is a song from the hardcore punk band Shai Hulud from their debut album Hearts Once Nourished with Hope and Compassion.
It is considered one of their most recognizable songs and is a live staple.
The opening guitar riff was a direct result of the sadness everyone felt due to Oliver Chapoy's mother dying.
The sample played before the song starts (on Solely Concentrating on the Negative Aspects of Life) is Bill Murray saying "It's gonna be cold.
Video on YouTube Brian Fair of Overcast & Shadows Fall and Jerry Villarroel of Morning Again made an appearance in the video.
