I am planning in running a Ph.D. student seminar next year on representation theory in the spirit of MIT Kan's Seminar where students give lectures on classical articles on representation theory that are typically not covered in a first course but that can none-the-less be covered in one week or so. I would like to amass a list of 12-20 articles or book chapters that should compose such a seminar. Examples would be

Demazure Inventiones 33 (1976) 271-272 "A very simple proof of Bott's theorem",

A. Beilinson, J. Bernstein, Localization de g-modules, C.R. Acad. Sci. Paris, 292 (1981), 15-18.

Chapter 4 of Chriss-Ginzburg "Representation Theory and Complex Geometry".

and non-examples should be the geometric Satake isomorphism or Zhu's modularity of characters of vertex algebras.

I am not sure if this question goes here or not, but ME seemed like the wrong place to ask. Since I found similar questions here like A request for suggestions of advanced topics in representation theory and A learning roadmap for Representation Theory I figured it was alright.
