I've come across Sleep Token here and there (mostly on Drumeo videos) but I've never listened to them, admittedly because of the visual. I have to say I'm surprised that they sound NOTHING like I thought they would.
With the exception of 'Vore', the vast majority of their music doesn't fit the aesthetic stylings, which I'm fairly sure is just done for theatrics and to embellish the lore behind the band, and they've created a tonne of lore.
A few stand out tracks for me are;
Atlantic - a delicate song that fans interpret to be about someone coming to in a hospital, following a tragic accident, and dealing with the grief and depression in blaming themselves for killing a friend in the accident.
Alkaline - straight up love song, trying to quantify and explain the qualities of someone you love so smittenly that you can't explain them clearly.
Chokehold - if the band actually sounded like expected based on their image, Chokehold would be their softer track. It thumps along with rythme with louder yet still clear lyrics and sounds closer to metal.
Ascensionism - follows a similar structure to Emergence in it's building up, but here it's more of a genre jump. The song is about trying to understand your partner in an abusive relationship, and realizing you're no better, you want the same thing from eachother but don't know how to get it, resulting in abuse.
