Echosmith, the Chino, California, indie pop group comprised of four siblings, headed to the East Coast on Monday night for a fun appearance on The Tonight Show Starring Jimmy Fallon. The group played a fresh rendition of “Let’s Love,” off of their 2013 debut album, Talking Dreams. It’s not an earth-shattering show by any measure, but it’s a bright, enjoyable little tune sung by sunny people — Fallon called them “one of the biggest breakout acts of 2015.” Check it out.
