Presley returned to the United States on March 2, 1960, and was honorably discharged with the rank of sergeant on March 5.[167] The train that carried him from New Jersey to Tennessee was mobbed all the way, and Presley was called upon to appear at scheduled stops to please his fans.[168] On the night of March 20, he entered RCA's Nashville studio to cut tracks for a new album along with a single, "Stuck on You", which was rushed into release and swiftly became a number one hit.[169] Another Nashville session two weeks later yielded a pair of his best-selling singles, the ballads "It's Now or Never" and "Are You Lonesome Tonight?",[170] along with the rest of Elvis Is Back! 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. Elvis's singing wasn't sexy, it was pornographic."[171] As a whole, the record "conjured up the vision of a performer who could be all things", in the words of 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".[172] Released only days after recording was complete, it reached number two on the album chart
