International (and galactic) treasure, Claire Boucher, aka GRIMES, performed live on The Tonight Show With Jimmy Fallon for the first time last night, and not surprisingly, the musician/producer/modern Beethoven killed it.

Not only killed it, but demolished it, and then rebuilt it, just to demolish it one more time.

Grimes performed "Flesh Without Blood" the infectious lead single off her terrific 2015 album Art Angels, and shredding on the bass guitar while belting out pristine vocals, the psyche-warped pop star served us some major glory.

To go on national TV and do the damn thing, all while staying true to your unabashed freakdom...it's truly a feat.

Go OFF, Grimes.
