Can You Spot What's Weird About Grimes' 'Tonight Show' Performance?

Grimes and her curious crew hit the Tonight Show stage on Wednesday to perform her Art Angels single "Flesh Without Blood." It was a technicolor spectacle with glitchy stripes of light and a shimmery blue hanging over the whole scene, her dancers busting out their signature robotic moves as Grimes and her partner in crime played a bouncy version of the song.

Grimes wore a Zac Posen ballgown, looking more ~Met Gala~ than she did at the Met Gala. Her arms were drenched in glitter as she thumbed the ever-present bass line on a red guitar, commanding her 808s simultaneously.

You gotta admit, seeing Grimes perform is impressive—she's got the presence, the pipes, the whole cornucopia of electronic sounds to orchestrate—but there was one thing that irked me about her Tonight Show appearance: Jimmy Fallon's introduction.
