Question: Isbell was born in Green Hill, Alabama, two miles from the Alabama/Tennessee state line, the son of interior designer mother Angela Hill Barnett and house painter Mike Isbell. Isbell's mother was only 17 years old (and his father 19 years old) when he was born and is the subject of a song, "Children of Children". Isbell's parents divorced, and he has two much younger half-siblings, Chantry Barnett and Emily Isbell. Isbell grew up in rural North Alabama.

Jason Isbell released his first solo album, Sirens of the Ditch, on July 10, 2007. In 2012, Isbell supported singer-songwriter Ryan Adams on his tour. Both played solo acoustic sets. On June 11, 2013, Isbell released his fourth solo album, Southeastern. Produced by Dave Cobb and featuring accompanying vocals by Kim Richey and Isbell's wife, Amanda Shires, Southeastern received overwhelmingly positive critical reviews, earning a score of 87 on Metacritic. Southeastern led to Isbell's clean sweep of the 2014 Americana Music Awards. Southeastern won Album of the Year, Isbell was named Artist of the Year, and the song "Cover Me Up" was named Song of the Year. NPR rock critic Ken Tucker listed Southeastern at No. 1 on his top ten albums of 2013. Isbell's record received praise by artists like Bruce Springsteen and John Prine. Isbell's music video for the song "Traveling Alone" features the Jackson House, a historic home in Moulton, Alabama. In 2014, his song "Cover Me Up" was used as the weather for the Welcome to Night Vale episode "Visitor". Isbell's fifth solo record, Something More Than Free, was released on July 17, 2015, on Southeastern Records. Dave Cobb produced, continuing the partnership created with Isbell on Southeastern. They recorded the album at Nashville's Sound Emporium studio with a full band. During the summer of 2015, Isbell was on a North American tour to promote the album, with four consecutive sold-out nights at the Ryman Auditorium in Nashville at the end of October. In April 2016, Isbell appeared on the BBC live-music show Later With Jools Holland, singing "The Life You Chose", one of the tracks from Something More Than Free. Isbell said that compared to Southeastern, Something More Than Free has a feeling of celebration, which reflects his upcoming fatherhood and a forward-facing momentum. One track on the record, "To a Band I Loved", is a love-letter to the band Centro-Matic, a now defunct band from Denton, Texas, Isbell played with back in his Drive-By Truckers days. Something More Than Free debuted at number 1 on Billboard Magazine's rock, folk and country record charts. Although Isbell had had critical success in the Americana genre, this was the first time he received such high ranking across genres. The album was well received, winning two Grammy awards for Best Americana Album and Best American Roots Song ("24 Frames"). On May 11, 2016, Isbell, a four-time winner, was nominated for three more Americana Music Honors & Awards: Album of the Year (Something More Than Free), Song of the Year ("24 Frames"), and Artist of the Year. He won the first two, while Chris Stapleton won Artist of the Year.

Question: 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.
