The Weeknd’s short film “Mania†arrived today, and even though Abel Tesfaye has a new haircut, his long video has all the usual suspects: a hot model (Anais Mali), a fast car, a dance club, and a large predatory cat. It’s like R&B Neon Demon, complete with a violent murder thrown in to surprise you — twist! If you want something that isn’t holiday-themed, take a break from the season of giving with this icy pop treat.
