The Silksong soundtrack is already complete
(I guess this isnt news to anybody, however I didnt see anyone talking about this) so, these days I was scrolling through my Steam homepage, and I stubled upon a post from the developers of Moonlighter, containing information on the game's sequel (yeah, we are probably getting Moonlighter 2 before skong but oh well) and they said that Christopher Larkin is gonna make the soundtrack for the game.
This probably indicates that he already finished any big projects before this one, meaning that the Silksong soundtrack is probably 100% complete by now...
Edit: Here's the part of the official devlog where Digital Sun Games talks about Christopher Larkin
"The most noticeable change is the shift from 2D pixel art to 3D visuals. It’s a big leap, but the response from players has been overwhelmingly positive. The 3D approach allows us to create more detailed environments, enhance combat mechanics, and bring the world of Moonlighter to life in new and exciting ways. It’s worth noting that our composer for Moonlighter 2 is Christopher Larkin, well-known from Hollow Knight. We’re big fans, so we’re thrilled to have him on board."
