Some (optional!) desiderata to guide your recommendation:
They probably have not been heard of around these parts.
They disagree with a consensus.
They have genuinely original thoughts.
You have updated from their views and/or been emotionally affected.
They’re actively doing some interesting thing(s) and seem effective at those things.
Reading/listening doesn’t feel like an obtuse poetic maze; they attempt to convey things relatively clearly.
Maybe they use an unusual method of communication.
Feel free to disregard these criteria if it doesn’t work for answering the question! :)
