On what date did Atco Records release the album where Pantera introduced a groove metal sound?
Pantera Pantera was an American heavy metal band from Arlington, Texas. The group was formed in 1981 by the Abbott brothers – drummer Vinnie Paul and guitarist Dimebag Darrell – along with lead vocalist Terry Glaze. Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original. Having started as a glam metal band, Pantera released four albums during the 1980s. 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. "Far Beyond Driven" (1994) debuted at number one on the "Billboard" 200.
Ascend (Greg Howe album) Ascend is the sixth studio album by guitarist Greg Howe, released on May 4, 1999 through Shrapnel Records. According to Howe, this is his least favourite album due in part to creative differences which arose with keyboardist Vitalij Kuprij during the making of the latter's 1997 album "High Definition". In the liner notes, Howe explains his decision to revisit the neoclassical style of his earlier work, however clarifying that "by no means is this a reflection of where I'm headed with my music in the future." The fifth track, "La Villa Strangiato", is a cover of an instrumental by progressive rock band Rush, from their 1978 album "Hemispheres".
