Anywhere in the world, nine dapper vocalists walk across the stage and immediately bring audiences to their feet.

They do so with nothing more than microphones in hand, grins ear-to-ear, witty banter on point, and an uncanny ability to belt out holiday staples, R&B smooth jams, and stadium anthems carried by style, swagger, and spirit. For as much as the story of Straight No Chaser belongs to the nine guys on stage, it also belongs to a devoted community of millions worldwide affectionately dubbed, “Chasers,” who cemented the a cappella collective’s status as an international phenomenon.
