Sonic Youth - Evol, Sister, Daydream Nation.
I would also count Bad Moon Rising, Goo, and Dirty as being part of a great run, but I know an easier arguement can be made for just the above three.
Radiohead - The Bends, OK Computer, Kid A. Hard to top that.
Converge - Jane Doe, You Fail Me, No Heroes.
With Boris it’s hard to say because of what can be considered as “proper” albums but Flood, Heavy Rocks, and Akuma No Uta are all lovely.
