Courtney Barnett Rocks So Very Hard on 'Fallon': Must-See Late Night Performance

Fresh off a Bonnaroo performance last weekend, Courtney Barnett stopped by The Tonight Show Starring Jimmy Fallon to perform her garage rock banger "Pedestrian at Best."

Dressed in a dope Chastity Belt shirt, Courtney really does it all here. Backed by only a drummer and bassist, she drives "Pedestrian" along with its raucous guitar line and, of course, ups the vocal ante for its humongous chorus. Do you prefer "I'll only disappoint YEEEEW" (the ways she sings on the album) or "I'll only disappoint YOU" like he sings here? Both are rad, really. Her bandmates also fill in some subtle background vocals once the second chorus kicks in.

This isn't Courtney's first rodeo on the talk-show circuit; back in March, she performed "Depreston" on Ellen.

Her album Sometimes I Sit and Think, Sometimes I Just Sit dropped this March and you can expect to see it on a lot of year-end "best of 2015" lists.
