Why u no do

Hey everyone, very new to the genre but turns out I absolutely love it. So I'm familiar with the rushmore type albums like Kite String, Sonic Excess, Odd Fellows Rest and such but given I'm a total newbie, what would we say are the essential listening/generally considered best sludge albums?

Go your hardest by the way, I like diving into the deep end so dont be scared to recommend any I guess 'advanced' level sludge albums if they're S tier
