First FX unveiled a provocative poster for “American Horror Story: Coven” that featured… let’s just go ahead and call it interracial group snake fellatio, but symbolic, probably. And the latest promo for the series takes that imagery even further, pairing up benign-sounding guitar strumming and female vocals with a female mouth being confronted with, opening up and swallowing a snake. Given the new season of the never-subtle series has for a central setting an embattled New Orleans coven and the prominence of Jessica Lange, Angela Bassett and Kathy Bates, no one would ever accuse the series of short-shrifting its formidable female characters, and last year the series directly dealt with themes of sexism, oppression and repression. So there’s no doubt this combination of sexualized imagery and ones of power and devouring are deliberate, as much as they’re also button-pushing. New season premieres October 9.
