IN: Darrell Lance Abbott (August 20, 1966 - December 8, 2004), also known as Dimebag Darrell and Diamond Darrell, was an American musician and songwriter who was a co-founder of Pantera alongside his brother Vinnie Paul, and founder of Damageplan. He was considered to be one of the driving forces behind groove metal. Abbott was shot and killed by a gunman while on stage during a performance with Damageplan on December 8, 2004, at the Alrosa Villa in Columbus, Ohio. He ranked No. 92 in Rolling Stone magazine's 100 Greatest Guitarists and No. 1 in the UK magazine Metal Hammer.

Abbott formed Pantera in 1981 with his brother Vinnie Paul on drums. Originally, he called himself Diamond Darrell Lance. The band was influenced with thrash metal acts such as Slayer, Megadeth, Venom, and Metallica as well as traditional metal bands such as Black Sabbath, Iron Maiden, Motorhead, and Judas Priest. Shortly after singer Phil Anselmo joined Pantera, Darrell was invited by Dave Mustaine to join Megadeth. Darrell was willing to join, but on the condition that Mustaine also hire his brother Vinnie on drums. As Mustaine already had a drummer, Chuck Behler, Darrell decided to stay with Pantera.  Pantera would go on to become a key formulator of the post-thrash subgenre of "groove" metal. It would not be until nine years after forming that Pantera saw its first piece of commercial success in its 1990 major label debut, Cowboys from Hell. Pantera's "groove" style came to fruition in its breakthrough album Vulgar Display of Power, released on February 25, 1992, which saw the replacement of the power metal falsetto vocals with a hardcore-influenced shouted delivery and heavier guitar sound. On Pantera's 1994 album Far Beyond Driven, Abbott, who'd been listed on all prior albums under the moniker "Diamond Darrell", was listed as "Dimebag Darrell". On the night before Pantera's live appearance at the Monsters of Rock in England's Donington Park, the Abbott brothers got involved in altercations at a local club with journalists from magazines Kerrang! and Raw.  Pantera began to suffer from mounting tensions between band members in the mid-1990s, largely due to vocalist Phil Anselmo's rampant drug abuse.  In 2001, the group went on hiatus, during which time Anselmo worked on side projects, such as Superjoint Ritual and Down. This caused more friction within the band, as the Abbott brothers kept waiting for Anselmo to become available to work with them again. The frustration with Anselmo led to their decision to disband Pantera in 2003.

input: Wednesday Morning, 3 A.M. sold only 3,000 copies upon its October release, and its poor sales led Simon to move to England where he had previously visited and played some gigs. He toured the small folk clubs, appearing on the same bill and befriending British folk artists such as Bert Jansch, Martin Carthy, Al Stewart, and Sandy Denny. He met Kathy Chitty, who became the object of his affection and is the Kathy in "Kathy's Song" and "America".  A small music publishing company, Lorna Music, licensed "Carlos Dominguez", a single Simon had cut two years prior as "Paul Kane", for a cover by Val Doonican that sold very well. Simon visited Lorna to thank them, and the meeting resulted in a publishing and recording contract. He signed to the Oriole label and released "He Was My Brother" as a single. Simon invited Garfunkel to stay for the summer of 1964. Near the end of the season, Garfunkel returned to Columbia for class, and Simon surprised his friends by saying that he would be returning to the States as well. He would resume his studies at Brooklyn Law School for one semester, partially at his parents' insistence. He returned to England in January 1965, now certain that music was his calling. In the meantime, his landlord, Judith Piepe, had compiled a tape from his work at Lorna and sent it to the BBC in hopes they would play it. The demos aired on the Five to Ten morning show, and were instantly successful. Oriole had folded into CBS by that point, and hoped to record a new Paul Simon album. The Paul Simon Songbook was recorded in June 1965 and featured multiple future Simon & Garfunkel staples, among them "I Am a Rock" and "April Come She Will". CBS flew Wilson over to produce the record, and he stayed at Simon's flat. The album saw release in August, and although sales were poor, Simon felt content with his future in England.  Meanwhile, in the United States, a late-night disc jockey at WBZ-FM in Boston played "The Sound of Silence", where it was popular with a college audience. It was picked up the next day along the East Coast of the United States, down to Cocoa Beach, Florida. Wilson, inspired by the folk rock sound of the Byrds' cover of "Turn! Turn! Turn!" and Dylan's "Like a Rolling Stone", created a rock remix of the song using studio musicians. The remix of "The Sound of Silence" was issued in September 1965, where it reached the Billboard Hot 100. Wilson had not informed the duo of his intention to remix the track; as such, Simon was "horrified" when he first heard it. Garfunkel graduated in 1965, returning to Columbia University to do a master's degree in mathematics.
