Looking for a new and heavier sound, Pantera replaced Glaze with Phil Anselmo in late 1986 and released "Power Metal" in 1988.  With its fifth album, 1990's "Cowboys from Hell", Pantera introduced a groove metal sound.  Pantera's sixth album, 1992's "Vulgar Display of Power", exhibited an even heavier sound.

Wexford, and Ellen Stafford of Carrick-on-Bannow, Co.  Wexford.  He attended Mount Sion in Waterford City, the first school founded and run by the Congregation of Christian Brothers.  The Irish Christian Brothers were staunch champions of Irish nationalism, the Irish Language Revival and Irish sports.  Mount Sion established a strong and enduring tradition of hurling, which filled the young and impressionable Jimmy with a lifelong enthusiasm.

Guitar solos took on character, hinting at Dimebag Darrell's later style.  It was also the last album to feature lead singer Terry Glaze.
