Question:
Charles Michael "Chuck" Schuldiner (May 13, 1967 - December 13, 2001) was an American singer, songwriter, and guitarist. He founded the pioneering band Death in 1983. Schuldiner is often referred to as "The Godfather of death metal", and his obituary in the January 5, 2002 issue of UK's Kerrang! magazine said that "Chuck Schuldiner was one of the most significant figures in the history of metal."
Schuldiner formed Death as Mantas in 1983 when he was just 16 years old. Original members were Schuldiner (guitar), Rick Rozz (guitar) and Kam Lee (drums and vocals). In January 1986, Schuldiner moved to Toronto and temporarily joined the Canadian band Slaughter. However, he quickly returned to continue the formation of Death.  Death underwent many lineup changes. With Chris Reifert, Schuldiner eventually released the first Death album, titled Scream Bloody Gore, in 1987. He continued with 1988's Leprosy with the line-up of former Mantas guitarist Rick Rozz and rhythm section Terry Butler on bass and Bill Andrews on drums, and 1990's Spiritual Healing, where guitarist James Murphy had replaced the fired Rozz in 1989.  After Spiritual Healing, Schuldiner stopped working with full-time band members, preferring to work with studio and live venue musicians, due to bad relationships with Death's previous rhythm section and guitarists. This earned Schuldiner something of a 'perfectionist' reputation in the metal community. Schuldiner had also fired his manager Eric Greif but settled and re-hired him before the recording of his next, influential release.  Death's breakthrough album, Human saw the band evolving to a more technical and progressive style, in which Schuldiner displayed his guitar skills more than ever. He continued in this style (and continued the success of the band) with 1993's Individual Thought Patterns, 1995's Symbolic, and finally The Sound of Perseverance in 1998. Throughout his career, Schuldiner was not afraid to take on controversial lyrical subjects, taking an anti-drug stance on "Living Monstrosity" and writing about abortion in "Altering the Future".  He put Death on hold after this to continue Control Denied, which he had been putting together prior to the release of The Sound of Perseverance, and released The Fragile Art of Existence in 1999. Control Denied also had other players from the latest Death album but featured a melodic metal vocalist. Schuldiner also played guitar in the "supergroup" Voodoocult on the album Jesus Killing Machine in 1994 and played a guest solo on Naphobia's 1995 release, Of Hell on the track "As Ancients Evolve" as a favor to the band's bassist at the time who was a friend of Schuldiner's. Schuldiner was also asked to be one of the many guest vocalists on Dave Grohl's 2001 Probot. Grohl, Napalm Death, Ozzy Osbourne, and Anthrax all increased efforts to raise funds for Schuldiner's medical bills with Grohl trying to involve Schuldiner on an album he was working on. In a 1999 interview Schuldiner spoke about why he didn't sing on the album The Fragile Art of Existence "...these vocals are all I ever wanted to do in Death but couldn't. I've had this dream of recording like that for years, and it seems like a dream come true. Tim Aymar is an amazing singer and this is the main difference. I think people will be surprised at the violence and strength of the album. Many people are expecting something like Iron Maiden, but, despite being one of my favorite bands, I didn't want to make an Iron Maiden-like album. I wanted to make an unpredictable album, just like I did in Death, I guess. I don't like to make predictable albums."

Question:
"Hound Dog" is a twelve-bar blues song written by Jerry Leiber and Mike Stoller. Recorded originally by Willie Mae "Big Mama" Thornton on August 13, 1952, in Los Angeles and released by Peacock Records in late February 1953, "Hound Dog" was Thornton's only hit record, selling over 500,000 copies, spending 14 weeks in the R&B charts, including seven weeks at number one. Thornton's recording of "Hound Dog" is listed as one of the Rock and Roll Hall of Fame's "500 Songs That Shaped Rock and Roll", and was inducted into the Grammy Hall of Fame in February 2013. "Hound Dog" has been recorded more than 250 times. The best-known version is the July 1956 recording by Elvis Presley, which is ranked number 19 on Rolling Stone magazine's list of the 500 Greatest Songs of All Time; it is also one of the best-selling singles of all time.
"Hound Dog" (G2WW-5935) was initially released as the B-side to the single "Don't Be Cruel" (G2WW-5936) on July 13, 1956. Soon after the single was re-released with "Hound Dog" first and in larger print than "Don't Be Cruel" on the record sleeve. Both sides of the record topped Billboard's Best Sellers in Stores and Most Played in Jukeboxes charts alongside "Don't Be Cruel", while "Hound Dog" on its own merit topped the country & western and rhythm & blues charts and peaked at number two on Billboard's main pop chart, the Top 100. Later reissues of the single by RCA in the 1960s designated the pair as double-A-sided.  While Presley was performing "Hound Dog" on television and his record was scaling the charts, Stoller, who had been on vacation in Europe, was returning on the ill-fated final voyage of the Andrea Doria. On July 26, 1956, Leiber met the just-rescued Stoller on the docks and told him, "We got a smash hit on Hound Dog," Stoller said, "Big Mama's record?" And Leiber replied: '"No. Some white guy named Elvis Presley." Stoller added: "And I heard the record and I was disappointed. It just sounded terribly nervous, too fast, too white. But you know, after it sold seven or eight million records it started to sound better." Leiber and Stoller tired of explaining that Presley had dropped most of their lyrics. For example, Leiber complained about Presley adding the line, "You ain't caught a rabbit, and you ain't no friend of mine", calling it "inane...It doesn't mean anything to me." Forty years later, Leiber told music journalist Rikky Rooksby that Presley had stamped the hit with his own identity: "(A) white singer from Memphis who's a hell of a singer--he does have some black attitudes--takes the song over ... But here's the thing: we didn't make it. His version is like a combination of country and skiffle. It's not black. He sounds like Hank Snow. In most cases where we are attributed with rock and roll, it's misleading, because what we did is usually the original record--which is R&B--and some other producer (and a lot of them are great) covered our original record."  By August 18, 1956, Peacock Records re-released Big Mama Thornton's original recording of "Hound Dog", backing it with "Rock-a-Bye Baby" (Peacock 5-1612), but it failed to chart.
