5 Seconds of Summer Give Technicolor Performance of 'Want You Back' on 'Tonight Show': Watch

5 Seconds of Summer brought their colorful power pop to the stage of The Tonight Show Starring Jimmy Fallon on Wednesday night (Apr. 11). The Australian four-piece performed their latest single, the upbeat heartbreak tune "Want You Back."

The boy band went for a simple stage setup that involved a solid white background, floor and drum riser. As they rocked through the song, multi-colored floodlights were projected onto the white surfaces, creating a bold and ever-changing effect. The colorful theme is likely pulled from the two music videos 5SOS has released for "Want You Back"; an official clip as well as a one-shot, stripped down clip for the acoustic version.

"Want You Back" is the first single from 5SOS' forthcoming third studio album, Youngblood, scheduled to drop this June. They are currently hitting the road throughout the U.S. on their 5SOS III tour.
