A song about a fallen friend

Memorial Day is a time when you look back to those who have passed away and you reflect on their life. Well, here's a song by the Mars Volta about a friend who commits suicide, via a drug overdose. Its depressing if you know the backstory and the video gives me chills everytime I watch it. I've teared up once or twice listening to this song because its such a departure from what these guys normally produce.
