Terrence Lee Glaze (born November 29, 1964) is an American singer and musician best known for his work with heavy metal band Pantera from 1981 to 1986. He appeared on the band’s first three albums during their « glam metal » era as the band’s lead vocalist and second guitarist before being replaced by Phil Anselmo in 1986.

Glaze was the lead singer of Pantera from 1982 to 1986, although he originally joined the band as a second guitarist in 1981, when the band was still rehearsing with original lead singer Donnie Hart. Glaze took over vocal duties in 1982 after Hart left the band, while still contributing some additional guitar parts on some of the band’s songs. His vocal range caught the attention of many record label A&Rs and he was credited for bringing Pantera to the forefront of heavy metal music. However, a dispute with the band’s musical direction ultimately led to Glaze leaving Pantera in 1986 with Glaze wanting to keep the glam metal style and the rest of the band wanting to be heavier.
