input: 1986 and 1987 saw the release of several landmark thrash metal albums that would prove influential to Pantera's developing musical style. Among the most prominent of these were Metallica's Master of Puppets, Slayer's Reign in Blood, Anthrax's Among the Living and Megadeth's Peace Sells... but Who's Buying? Terrence Lee's glam approach did not fit the band's developing style and he and the other members parted ways, beginning a search for his replacement. Pantera initially turned to Matt L'Amour, a David Coverdale lookalike. He sang a number of shows with Pantera in Los Angeles during the winter of 1986, but it became immediately apparent that L'Amour could not hit the high notes Glaze (or Anselmo) was capable of. Together with his lack of stage presence, this meant Pantera could only play cover songs so L'Amour departed. Pantera next auditioned El Paso native Rick Mythiasin, later to sing for Steel Prophet and Agent Steel; however, cultural and image differences - Mythiasin failed to adapt to the Southern culture of the other members - meant his tenure was even shorter than that of L'Amour. A former schoolmate of the Abbott brothers, David Peacock of the band Forced Entry (who had supported Warlock), joined the band as lead vocalist in the spring of 1986, but despite Pantera doing most of the work for their fourth album during the summer with Peacock, Rex and the Abbotts found Peacock's voice to be unsuited to the musical direction Pantera wished for. By the end of the year, Pantera even revisited original frontman Donny Hart, but Hart himself knew he was not the man Pantera were seeking and Jerry Abbott was to fire him. During 1986, New Orleans native Phil Anselmo had always heard Pantera were looking for a singer. At the end of the year, they invited him to audition, and the nineteen-year old Anselmo immediately became a member of the band. Anselmo had previously been the vocalist for the bands Samhain (not to be confused with Glenn Danzig's band of the same name) and Razor White. Upon playing with Pantera, Anselmo immediately clicked with the other three members. More than just the band's image was changing, however. In 1988, Pantera released its first album with Anselmo, titled Power Metal. Power Metal, like Pantera's previous three albums, was released on Metal Magic Records, but showcased a change in their sound. By far the band's heaviest album at this point, Power Metal was a mix of 1980s hard rock and thrash metal, sometimes blending both styles in a single song. Complementing the band's new sonic approach were Anselmo's harder-edged vocals compared to those of Terrence Lee. After the release of Power Metal, the band members decided to seriously reconsider their glam metal image and sound. Referring to the band's spandex appearance, Vinnie Paul remarked at a band meeting that "These magic clothes don't play music; we do. Let's just go out there and be comfortable -- jeans, t-shirt, whatever--and see where it goes." The band members would later ignore their independent releases, including Power Metal, as they sculpted a new, heavier image to accompany their later groove metal sound. Their four independent albums are not listed on the band's official website and have become hard-to-find collector's items.

input: Teenagers Rosalind Ashford and Annette Beard first became acquainted after a local music manager hired them to be members of a girl group he named The Del-Phis. Ashford & Beard, along with then-lead vocalist Gloria Williams, performed at local clubs, private events, church benefits, YMCA events and school functions. They were also being coached by Maxine Powell at Detroit's Ferris Center. One of the group's first professional engagements was singing background for singer Mike Hanks. The group originally had up to six members, shortened to four. After another member left the group, she was replaced by Alabama-born vocalist Martha Reeves, who had been a member of a rival group, the Fascinations and had also been a member of another group, the Sabre-Ettes. In 1960, the group signed their first recording contract with Checker Records, releasing the Reeves-led "I'll Let You Know". The record flopped. The group then recorded for Checkmate Records, a subsidiary of Chess Records, recording their first take of "There He Is (At My Door)". That record, featuring Williams on lead vocals, also flopped. Briefly separated, Reeves returned to a solo career performing under the name Martha LaVaille, in hopes of getting a contract with emerging Detroit label Motown. After Motown staffer Mickey Stevenson noticed Reeves singing at a prominent Detroit club, he offered her his business card for an audition. Reeves showed up at Motown on a wrong date (Motown auditions were held at Thursdays, while Reeves showed up to Motown's Hitsville USA studios on a Tuesday). Stevenson, initially upset, told Reeves to look out for clients and other matters. Soon Reeves became Stevenson's secretary and later was responsible for helping acts audition for the label. By 1961, the group, now known as The Vels, were recording background vocals for Motown acts. Prior to her success as lead singer of The Elgins, Sandra Edwards (then going by her surname Maulett) recorded the song "Camel Walk", in 1962, which featured the Vels in background vocals. That year, the quartet began applying background vocals for emerging Motown star Marvin Gaye, singing on Gaye's first hit single, "Stubborn Kind of Fellow" After Mary Wells failed to make a scheduled recording session feigning a short illness, the Vels recorded what was initially a demo recording of "I'll Have to Let Him Go". Motown was so impressed by the group's vocals - and Martha's lead vocals in the song - that the label CEO Berry Gordy offered to give the group a contract. Figuring that being in show business was too rigorous, Williams opted out of the group. With Williams out, the remaining trio of Ashford, Beard and Reeves renamed themselves The Vandellas, after Detroit's Van Dyke Street and Reeves' favorite singer, Della Reese.
