Singer/songwriter Nate Ruess is a versatile pop powerhouse that can bring out a fiery passion in any collaborator. Starting off as the charismatic frontman for indie band The Format, then alt-rock hitmakers Fun.—who dominated the charts in 2012 with the triumphant “We Are Young,” featuring Janelle Monae—Ruess has also cowritten empowering anthems for heavy hitters like P!nk, Eminem, and even Beach Boys legend Brian Wilson.
