Alan Walker & Noah Cyrus Perform 'All Falls Down' on 'The Tonight Show': Watch

Big things are in motion for Norway's black-clad ninja Alan Walker. The "Faded" producer was just announced on the Coachella 2018 lineup, and he's making rounds in support of his latest single "All Falls Down" with vocal collaborator Noah Cyrus in tow.

The pair recently took the stage on The Tonight Show Starring Jimmy Fallon, joined by a full band, rockin' like a regular yin and yang. Cyrus belts out her part playfully in a puffy white getup. She comes around to join Walker on the keys, and while we can't say for sure, we bet he's smiling big under that mask.

Walker recently came by the Billboard office to say what's up to Billboard Dance founder Matt Medved and fill us in on his big plans for 2018. Definitely check out the chat, and catch The Tonight Show performance below.
