Christopher Sernel, also known as Oh, Hush!, is an American recording artist and Grammy-nominated producer.

Early in his career, Sernel reveled in anonymity under the Oh, Hush! alias, not performing shows or giving interviews and relying heavily on word of mouth in contrast to usual music industry norms.

Shortly after the release of the debut The Yellow Album, Oh, Hush! was signed by Mike Caren of Artist Publishing Group. Oh, Hush! has composed music for commercials for companies such as Dunkin' Donuts, Wal-Mart, & Nutella.
