Love her or hate her, you’ve got to admit that Lady Gaga knows how to make a music video. Her clips always have been a mixture of high-art posturing and knowing nods to pop-culture ephemera, and “Judas” is no different. While it’s not filled with blink-and-you’ll-miss-it references like “Telephone” or odes to German Expressionism like “Alejandro,” there’s still plenty to wrap your eyes around in “Judas,” offering a mixture of the sacred and the profane. Gaga merges mentions to religious iconography and cult biker flicks (and pretty much everything in between) in the video, and so, we decided to take notes. Here’s our “Judas” pop-culture cheat sheet, alphabetized for your perusing pleasure … you can’t tell your Botticellis from your Brandos without it.
