Presley, on guitar and accompanied by lead guitarist Scotty Moore and bassist Bill Black, was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and blues.

In 1955, drummer D. J. Fontana joined to complete the lineup of Presley's classic quartet and RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who managed him for the rest of his career.

[49] During the next few days, the trio recorded a bluegrass song, Bill Monroe's "Blue Moon of Kentucky", again in a distinctive style and employing a jury-rigged echo effect that Sam Phillips dubbed "slapback".

[52][53] A combination of his strong response to rhythm and nervousness led Presley to shake his legs as he performed: His wide-cut pants emphasized his movements, causing young women in the audience to start screaming.

[79] Extending his by-now customary backup of Moore, Black, Fontana, and Hayride pianist Floyd Cramer—who had been performing at live club dates with Presley—RCA Victor enlisted guitarist Chet Atkins and three background singers, including Gordon Stoker of the popular Jordanaires quartet.

[90] He had attended several shows by Freddie Bell and the Bellboys in Vegas and was struck by their cover of "Hound Dog", a hit in 1953 for blues singer Big Mama Thornton by songwriters Jerry Leiber and Mike Stoller.

[156] Media reports echoed Presley's concerns about his career, but RCA Victor producer Steve Sholes and Freddy Bienstock of Hill and Range had carefully prepared: armed with a substantial amount of unreleased material, they kept up a regular stream of successful releases.

[157] Between his induction and discharge, Presley had ten top-40 hits, including "Wear My Ring Around Your Neck", the bestselling "Hard Headed Woman", and "One Night" in 1958, and "(Now and Then There's) A Fool Such as I" and the number-one "A Big Hunk o' Love" in 1959.

The album features several songs described by Greil Marcus as full of Chicago blues "menace, driven by Presley's own super-miked acoustic guitar, brilliant playing by Scotty Moore, and demonic sax work from Boots Randolph.

"[164] The record "conjured up the vision of a performer who could be all things", according to music historian John Robertson: "a flirtatious teenage idol with a heart of gold; a tempestuous, dangerous lover; a gutbucket blues singer; a sophisticated nightclub entertainer; [a] raucous rocker".

[180] In the first half of the decade, three of Presley's soundtrack albums were ranked number one on the pop charts, and a few of his most popular songs came from his films, such as "Can't Help Falling in Love" (1961) and "Return to Sender" (1962).

Parker oversaw a major promotional push, and International Hotel owner Kirk Kerkorian arranged to send his own plane to New York to fly in rock journalists for the debut performance.

As music historian John Robertson noted, The authority of Presley's singing helped disguise the fact that the album stepped decisively away from the American-roots inspiration of the Memphis sessions towards a more middle-of-the-road sound.

On January 14, Aloha from Hawaii aired live via satellite to prime-time audiences in Japan, South Korea, Thailand, the Philippines, Australia, and New Zealand, as well as to U.S. servicemen based across Southeast Asia.

[272] Presley's cousin, Billy Smith, recalled how he would sit in his room and chat for hours, sometimes recounting favorite Monty Python sketches and his past escapades, but more often gripped by paranoid obsessions.

In the first, shot in Omaha on June 19, Presley's voice, Guralnick writes, "is almost unrecognizable, a small, childlike instrument in which he talks more than sings most of the songs, casts about uncertainly for the melody in others, and is virtually unable to articulate or project".

[274] Two days later, in Rapid City, South Dakota, "he looked healthier, seemed to have lost a little weight, and sounded better, too", though, by the conclusion of the performance, his face was "framed in a helmet of blue-black hair from which sweat sheets down over pale, swollen cheeks".

[291] While a 1981 trial of Presley's main physician, George C. Nichopoulos, exonerated him of criminal liability, the facts were startling: "In the first eight months of 1977 alone, he had [prescribed] more than 10,000 doses of sedatives, amphetamines, and narcotics: all in Elvis' name."

[324] Paul Friedlander described rockabilly as "essentially ... an Elvis Presley construction", with the defining elements as "the raw, emotive, and slurred vocal style and emphasis on rhythmic feeling [of] the blues with the string band and strummed rhythm guitar [of] country".

[325] In "That's All Right", the Presley trio's first record, Scotty Moore's guitar solo, "a combination of Merle Travis–style country finger-picking, double-stop slides from acoustic boogie, and blues-based bent-note, single-string work, is a microcosm of this fusion".

"[329] At RCA Victor, Presley's rock and roll sound grew distinct from rockabilly with group chorus vocals, more heavily amplified electric guitars,[330] and a tougher, more intense manner.

"[344] Marsh describes the vocal performance on "Can't Help Falling in Love" as one of "gentle insistence and delicacy of phrasing", with the line "'Shall I stay' pronounced as if the words are fragile as crystal".

"[354] Presley was always "able to duplicate the open, hoarse, ecstatic, screaming, shouting, wailing, reckless sound of the black rhythm-and-blues and gospel singers", writes Pleasants, and also demonstrated a remarkable ability to assimilate many other vocal styles.

[358] The persistence of such attitudes was fueled by resentment over the fact that Presley, whose musical and visual performance idiom owed much to African-American sources, achieved the cultural acknowledgement and commercial success largely denied his black peers.

[369] Brett Farmer places the "orgasmic gyrations" of the title dance sequence in Jailhouse Rock within a lineage of cinematic musical numbers that offer a "spectacular eroticization, if not homoeroticization, of the male image".

"[371] Reinforcing Presley's image as a sex symbol were the reports of his dalliances with Hollywood stars and starlets, from Natalie Wood in the 1950s to Connie Stevens and Ann-Margret in the 1960s to Candice Bergen and Cybill Shepherd in the 1970s.

He's worshiped as a god today because in addition to inventing rock and roll he was the greatest ballad singer this side of Frank Sinatra—because the spiritual translucence and reined-in gut sexuality of his slow weeper and torchy pop blues still activate the hormones and slavish devotion of millions of female human beings worldwide.

"[378] President Jimmy Carter remarked on Presley's legacy in 1977: "His music and his personality, fusing the styles of white country and black rhythm and blues, permanently changed the face of American popular culture.

[b] Presley's rankings for top ten and number-one hits vary depending on how the double-sided "Hound Dog/Don't Be Cruel" and "Don't/I Beg of You" singles, which precede the inception of Billboard's unified Hot 100 chart, are analyzed.

[4] It reads Aron on most official documents produced during his lifetime, including his high school diploma, RCA Victor record contract, and marriage license, and this was generally taken to be the proper spelling.
