I've done a TON of videos on FromSoft's music including Bloodborne. Check em out over here: https://www.youtube.com/watch?v=4nQexcuDPAw&list=PLOVEmfXEEAUA5IBCrgtZgKg-iYEEbMigM&index=2

15:57 “Sounds like you are doomed” man you are so skilled at reading the game by the ost. If you are killed in the second phase Messmer literally says: “Embrace thine oblivion, as shall I”. So basically messmer knows no matter the outcome, he is doomed, for its death or his curse that now is released

bro in the gameplay clutched up; zero flasks and one shot. true soulsborne moment there

"Duty" is basically all that Messmer is. He's a shell of a man, simply existing to serve his mother. He's only here to carry out a crusade for the sake of a mother that hates him for something he can't control.

Take a look at Midra’s OST. It’s amazing

'That' portion hits me hard. As you've said, with the descending chromatics, it's like Messmer is falling to 'oblivion' (as he mentions if he kills you during the 2nd phase), all the while the voices try in desperation to ascend, just like how Messmer is also desperately reaching or calling out to his mother who has abandoned him.

Messmer is such a tragic character. And the music nails it PERFECTLY.

15:23 you really do get the vision of messmer falling away from Marika and into the darkness of the abyss

The rhythm you are hearing at 3:43 is Radagon's theme, pretty cool!

The ability of this man to listen to the OST and get so much about the character/theme from it is incredible. Speaks volumes as to how much thought is put into each track and how good you are at analyzing it!

After all the hype built around him, I expected an epic theme song for him. After reading his story, I realized the sadness and rage in his theme fit him perfectly. It sounds a bit like title theme music, and there is a good reason behind it. Since you have started playing the game, I won't give you spoilers. Thanks for the amazing reaction, as always!

The final chorus makes me think of angels falling from heaven - the grandeur, doom and despair of it. Considering Messmer's heavy parallels with Lucifer I think that's exactly the idea Fromsoft is trying to evoke.

The title music motif you keep hearing is actually the OST of Radagon’s fight, Messmer’s father!

Oh I really really hope your cover midra, lord of frenzied flame. Best track in the entire game imo, it sounds so incredibly evil

During the phase transition cutscene, the choir mimicking the harmony is playing the two notes backwards. Instead of sad, disturbing, sad, disturbing...as the harmony was played during the first phase (and sounds similar to the plin-plong of the main menu theme), the choir goes disturbing, sad, disturbing, sad. My crackpot theory is this harmony is representative of Marika's golden order. During the first phase of Messmer's fight, he is very much acting in accordance with Marika's wishes, as he was forced due to Marika's seal. In the phase transition, Messmer breaks this seal and unleashes the abyss from within him. This moment is an ultimate blasphemy against Marika's order, and it is fitting that the harmony be played upside down.

He is such a central figure of the DLC and his fight is amazing, at first I was a bit disappointed by the OST but the more I hear it the more it hits the feelings.
I wanted to suggest a song I didn't see many people suggest it is super emotional:
Those united in common cause also from this DLC

He’s always spot on with the themes of the boss fights without even having seen them. He lets the music tell him everything

“It’s like an Eternal fall” Messmer has the Abysal serpent. I’m amazed you can bring so much more meaning just by listening to music, amazing!!

“Those stripped from the Grace of Gold shall all meet death… in the embrace of Messmers Flame”🔥

Watching these feels like the composers are writing the lore out in a secret language and sending it to Davi so he can decipher it

Mesmer was fooled into an ethnic cleansing in behest of his mother. And then, he was abandoned. Only until the moment he dies, he realizes he was fooled, lied to and forsaken
