Delving into Stravinsky

I am currently preparing a contribution for a Stravinsky volume that kind of absorbs me. The chapter will focus on analytical examinations of Old Igor’s music, confronting historical writings (starting with Messiaen’s and Boulez’s analyses of the Sacre) with contemporary approaches. Beyond the ubiquitous Taruskin, Kholopov, Straus, Horlacher, et alii: is there anything notable or indispensable in Stravinsky studies that you think I should care about and include in my survey? Any leads and opinions are much appreciated.
