During her attempted career as a conventional top-40 type, Sky Ferreira never made it as far as a late-night TV performance. Instead, she had to reinvent herself as a dead-eyed stoner-pop queen and link up with Dev Hynes, a makeover that resulted in the great single “Everything Is Embarrassing.” And last night, she made that late-night debut, singing the song on Fallon while the Roots backed her up and clouds of dry ice wafted up from the floor. It’s easy to be cynical about something like that, but Ferreira has some serious presence, and she cut an imposing and fierce figure on the stage last night. This is one of those Fallon performances that you should definitely watch, and it’s below.

Ferreira’s Ghost EP is out now on Capitol.
