Watch One Direction Softly Croon 'Night Changes' at 2014 AMAs

UK boy band also picks up multiple awards, including Favorite Band, Duo or Group

In contrast to bombastic performances by Taylor Swift and Iggy Azalea, One Direction took an understated approach to their gentle romantic ballad "Night Changes" at Sunday night's American Music Awards.

The group performed the single from their latest album Four in the middle of a simulated field, showcasing each of the five singers' vocals.

One Direction is shaping up to have a big night at the AMAs, winning Artist of the Year, Favorite Band, Duo or Group – Pop/Rock and Favorite Pop/Rock Album (for 2013's Midnight Memories).

"These songs split the difference between big, splashy Eighties pop rock and more elegant Seventies flavors," Jon Dolan wrote in his review of Four. "As always, the vocal duties are divvied up in ways that highlight the singers' similarities, placing weapons-grade hottie Harry Styles and take-him-or-leave-him Irishman Niall Horan in the same democratic swirl of desire.
