Found the following article online, use it to answer the question: What is the last name of the person who is often referred to as the "King of Rock and Roll"? Elvis Aaron Presley (January 8, 1935 August 16, 1977) was an American singer and actor. Regarded as one of the most significant cultural icons of the 20th century, he is often referred to as the "King of Rock and Roll" or simply "the King". Presley was born in Tupelo, Mississippi, and relocated to Memphis, Tennessee, with his family when he was 13 years old. His music career began there in 1954, recording at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Accompanied by guitarist Scotty Moore and bassist Bill Black, Presley 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 would manage him for more than two decades. Presley's first RCA single, "Heartbreak Hotel", was released in January 1956 and became a number-one hit in the United States. With a series of successful network television appearances and chart-topping records, he became the leading figure of the newly popular sound of rock and roll. His energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, made him enormously popularand controversial. In November 1956, Presley made his film debut in Love Me Tender. Drafted into military service in 1958, Presley relaunched his recording career two years later with some of his most commercially successful work. He held few concerts however, and guided by Parker, proceeded to devote much of the 1960s to making Hollywood films and soundtrack albums, most of them critically derided. In 1968, following a seven-year break from live performances, he returned to the stage in the acclaimed television comeback special Elvis, which led to an extended Las Vegas concert residency and a string...

Found the following article online, use it to answer the question: What is the full name of the group whose music had begun to be labeled as progressive rock by the press in the late 1960s? Considered one of the UK's first psychedelic music groups, Pink Floyd began their career at the vanguard of London's underground music scene. Some categorise their work from that era as space rock. According to Rolling Stone: "By 1967, they had developed an unmistakably psychedelic sound, performing long, loud suitelike compositions that touched on hard rock, blues, country, folk, and electronic music." Released in 1968, the song "Careful with That Axe, Eugene" helped galvanise their reputation as an art rock group. Other genres attributed to the band are experimental rock, acid rock, proto-prog, experimental pop (while under Barrett). and psychedelic pop, By the late 1960s, the press had begun to label their music progressive rock. O'Neill Surber comments on the music of Pink Floyd: Rarely will you find Floyd dishing up catchy hooks, tunes short enough for air-play, or predictable three-chord blues progressions; and never will you find them spending much time on the usual pop album of romance, partying, or self-hype. Their sonic universe is expansive, intense, and challenging ... Where most other bands neatly fit the songs to the music, the two forming a sort of autonomous and seamless whole complete with memorable hooks, Pink Floyd tends to set lyrics within a broader soundscape that often seems to have a life of its own ... Pink Floyd employs extended, stand-alone instrumentals which are never mere vehicles for showing off virtuoso but are planned and integral parts of the performance. In 1968, Wright commented on Pink Floyd's sonic reputation: "It's hard to see why we were cast as the first British psychedelic group. We never saw ourselves that way ... we realised that we were, after all, only playing for fun ... tied to no particular form of music, we could do whatever we wanted ... the emphasis ... [is] firmly on spontaneity and improvisation." Waters gave a less enthusiastic assessment of the band's early sound: "There wasn't anything 'grand' about it. We were laughable. We were useless. We couldn't...

Found the following article online, use it to answer the question: What is the first name of the person who used Gretsch model guitars on his early recordings? When Harrison joined the Quarrymen in 1958 his main guitar was a Hofner President Acoustic, which he soon traded for a Hofner Club 40 model. His first solid-body electric guitar was a Czech-built Jolana Futurama/Grazioso. The guitars he used on early recordings were mainly Gretsch models, played through a Vox amplifier, including a Gretsch Duo Jet that he bought secondhand in 1961, and posed with on the album cover for Cloud Nine. He also bought a Gretsch Tennessean and a Gretsch Country Gentleman, which he played on "She Loves You", and during the Beatles' 1964 appearance on The Ed Sullivan Show. In 1963 he bought a Rickenbacker 425 Fireglo, and in 1964 he acquired a Rickenbacker 360/12 guitar, which was the second of its kind to be manufactured. Harrison obtained his first Fender Stratocaster in 1965 and first used it during the recording of the Help! album that February; he also used it when recording Rubber Soul later that year, most notably on the song "Nowhere Man".In early 1966 Harrison and Lennon each purchased Epiphone Casinos, which they used on Revolver. Harrison also used a Gibson J-160E and a Gibson SG Standard while recording the album. He later painted his Stratocaster in a psychedelic design that included the word "Bebopalula" above the pickguard and the guitar's nickname, "Rocky", on the headstock. He played this guitar in the Magical Mystery Tour film and throughout his solo career. In July 1968, Clapton gave him a Gibson Les Paul, which Harrison nicknamed "Lucy". Around this time, he obtained a Gibson Jumbo J-200 acoustic guitar, which he subsequently gave to Dylan to use at the 1969 Isle of Wight Festival. In late 1968 Fender Musical Instruments Corporation gave Harrison a custom-made Fender Telecaster Rosewood prototype, made especially for him by Philip Kubicki. In August 2017, Fender released a "Limited Edition George Harrison Rosewood Telecaster" modelled after a Telecaster that Roger Rossmeisl originally created for Harrison.
