Up to Vulgar Display of Power, Pantera's music was fairly strictly along the lines of classic heavy metal -- with singing and screaming in the vocals (although the screaming is more high pitched than is normally found in nu metal vocals, for example) and the extravagant riffs and soloss of guitarist Dimebag Darrell. However, Phil Anselmo's vocals in particular have developed considerably since then, becoming more and more influenced by the singer's black metal influences.
They have toured as part of the Ozzfest (both in the United States and United Kingdom) and with support from Powerman 5000.
