Frank Mullen, (born January 1970) is the
lead vocalist of the American
death metal band
Suffocation, and met band mates
Mike Smith and
Terrance Hobbs in high school. He is recognized to be among the first to bring low-pitched vocals in death metal. His approach on
Effigy of the Forgotten could be considered to be the "blueprint" to the
death growls as we know it today. Unlike some death metal vocalists, his lyrics are pronounced more clearly. He achieves this by simply opening his mouth wider, but still retaining his low-pitched growls.
