Cemetery Gates

"Cemetery Gates" is a song by heavy metal band Pantera. The song is the fifth track from Cowboys from Hell, the band's fifth album and second with lead singer Phil Anselmo (though the band considers it their first "true" album, officially ignoring their earlier independent releases as it was their first album with the groove metal genre). "Cemetery Gates" showcases Anselmo's vocal ability and range, concluding with screaming high notes answered by Dimebag Darrell on guitar in a trade off. This is the longest song Pantera ever recorded, clocking in at 7:03.
