Echosmith stopped by The Tonight Show Starring Jimmy Fallon last night to perform their single, "Cool Kids." You can check out a video of the performance below. Let us know how you think they did.

The radio smash "Cool Kids" is taken from the band's latest album, Talking Dreams, which is out now via Warner Bros. Records. The song was recently certified Platinum for sales of over 1 million. If you missed it, AP recently took vocalist Sydney Sierota on a shopping spree.
