"New boss Ferryman could be referencing "The Ferryman", a Maudlin of the Well song. The album "bath" it's from uses a lot of water samples and wet tones like at the end of "The Ferryman" and "Interlude 2". Also pipe organs that link to the final boss of Act 2."

ENCORES

0-E: THIS HEAT, AN EVIL HEAT (thanks, Veles and STGG)

(the second half of the O-E title could also be a reference to Oxbow's 2002 album "An Evil Heat", as Hakita's rated a couple of their albums on RYM)

PRIME SANCTUMS

P-1: SOUL SURVIVOR

[tezchi]

5-2 waves of the starless sea is a reference to natural snow buildings' waves of the random sea

[FÁRIO "JABRONI" VEVO]

aye thanks for reminding me folks. only had proper time to get back into this game now after the update, but i'm updating this list rn

[STGG]

the second half of the O-E title could also be a reference to Oxbow's 2002 album "An Evil Heat", as Hakita's rated a couple of their albums on RYM

[Veles]

With regards to the new Encore levels:

I believe 0-E is a reference to two albums: Deceit's 1981 album "This Heat", and Primal Scream's 2002 album "Evil Heat"

1-E Is most likely a reference to the album "Then Fell The Ashes" by TwinSinisterMoon

[Riddy]

Really late to this, but the first testament in 0-S says "Let the evil of their own lips consume them" which is probably a reference to the Lingua Ignota album "Let The Evil Of His Own Lips Cover Him". Additionally, the "May your woes be many, and your days few" might be a reference to her song Butcher Of The World, where she says "May your foes be many, may your days be few".

[mee]

ik this is like super late but schism might also be referencing anthrax as theres a song by them with the same name :P

[dynamite dog woman (they/them)]

Great list, btw Soul Survivor might be a refrence to the Rolling Stones song of the same name.

[FÁRIO "JABRONI" VEVO]

it's what i thought too but captain fa(it)lcon in the comments said it wasn't

[The Foul Mold]

is "shot in the dark" not a reference to the famous ozzy osbourne song?

[drmeds.]

Nice list, been curious about these for a while. As some have pointed out before, 0-2 is a pretty obvious Madvillain / MF DOOM reference with "Meatgrinder".

I also believe that 2-1 "Bridgeburner" is likely to refer to the doom mapper of the same name. I vaguely remember Hakita mentioning him in an older In The Keep episode.
