Glenn started in the music business at the age of 11 - first as a drum roadie, and then as a bass player in a few local garage bands. Glenn had never taken vocal lessons, but the first time he auditioned for the role of a vocalist, he was surprised at the powerful voice he could achieve. His vocal prowess soon got him noticed in the local scene. Throughout his teenage years he sang for several local bands, such as Talus and Whodat And Boojang - most of which played half original songs and half Black Sabbath songs.
