The Black Parade Is Dead! is MCR's final performance as their onstage characters, the Black Parade. The Black Parade centres around a dying character called The Patient, who reflects on events in his life while he is confronted by Death in the form of his fondest memory, that of his father bringing him to see a marching band. This is based on frontman Gerard Way's belief that death comes to a person in the form of their fondest memory. The band is seen in their Black Parade uniforms throughout the performance, and during the first song "The End", Gerard Way is seen taking the role of The Patient, before tearing off his hospital gown to reveal his uniform. Behind the band is the backdrop seen on the video for Welcome to the Black Parade and the poster seen within the Black Parade CD case. On Bob Bryar's drums, the gas mask of the character Mother War can be seen. Way states in the track The Black Parade Is Dead! that the performance in Mexico was their way of "properly killing them (the Black Parade) off". The show is decorated with various lights and confetti. Fire is used to effect during the performance of "Mama" and "Famous Last Words". The film ends with a credit sequence featuring the hidden track from The Black Parade, "Blood". Gerard Way also reveled on disc two what the untitled track was in October of 2014 it is called "Someone Out There Loves You". This was stated via a redditt AMA reported on by Alt Press.
The album's official Web site went online on May 5, 2008 and is open for orders of all the limited and standard editions. Once an order is made, the customer gains access to download three free DRM-free tracks: "Dead!", "Mama", "Welcome to the Black Parade". These tracks were recorded from the band's performance at the Palacio de los Deportes and they are on the album itself. Also, to tie in with the whole finality of the Black Parade's death, the Black Parade website has been changed to a graphic of a flatline.
A limited-edition version with all of the album's contents, a death certificate and a mask designed by one of the band's members were also available, but are now sold out. This edition is housed in a coffin-shaped box. There are a total of five masks, one designed by each member, but only one is inside the packaging and is selected randomly. The masks can now be purchased separately or in a group of 4 on the band's website. The album is also available in explicit and clean editions.
In March 2009, the band made an announcement on their official website that they were releasing the encore set from the Mexico City show, in which they came out with Three Cheers For Sweet Revenge style clothing and the stage set up like the Revenge tour, and played nine songs from the album. It came with a vest, and the videos were put onto a special bullet shaped USB flash drive.
