What’s alleged to be a demo from Lady Gaga’s eternally upcoming Artpop popped up online last night, and it’s a little bit confusing. How many songs are contained herein under the moniker “Aura”? At least 8 by my account. I like to think that the opening passage is a response to that tepid Lana Del Rey diss track with its over the top noir tomfoolery. Elsewhere there’s the chorus to a club-pop ballad, hints of brostep, trance, some spazzy surf-guitar western, and about a half dozen other genre divergences. Anyway, don’t let your kids grow up to sort of know what art is, future parents of the world.
