of Johnson's disparate influences. The form, including the wordless last verse, follows Leroy Carr's last hit "When the Sun Goes Down"; the words of the last sung verse come directly from a song Blind Lemon Jefferson recorded in 1926. Johnson's last recording, "Milkcow's Calf Blues" is his most direct tribute to Kokomo Arnold, who wrote "Milkcow Blues" and influenced Johnson's vocal style. "From Four Until Late" shows Johnson's mastery of a blues style not usually associated with the Delta. He croons the lyrics in a manner reminiscent of Lonnie Johnson, and his guitar style is more that of a ragtime-influenced player like Blind Blake. Lonnie Johnson's influence is even clearer in two other departures from the usual Delta style: "Malted Milk" and "Drunken Hearted Man". Both copy the arrangement of Lonnie Johnson's "Life Saver Blues". The two takes of "Me and the Devil Blues" show the influence of Peetie Wheatstraw, calling into question the interpretation of this piece as "the spontaneous heart-cry of a demon-driven folk artist". Legacy Early recognition and reviews Famed producer John Hammond was an early advocate of Johnson's music. Using the pen-name Henry Johnson, he wrote his first article on Robert Johnson for the New Masses magazine in March 1937, around the time of the release of Johnson's first record. In it, he described Johnson as "the greatest Negro blues singer who has cropped up in recent years... Johnson makes Leadbelly sound like an accomplished poseur." The following year, Hammond hoped to get Johnson to perform at a December 1938 From Spirituals to Swing concert in New York City, as he was unaware that Johnson had died in August. Instead, Hammond played two of his recordings, "Walkin' Blues" and "Preachin' Blues (Up Jumped the Devil)", for the audience and "praised Johnson lavishly from the stage". Music historian Ted Gioia noted "Here, if only through the medium of recordings, Hammond used his considerable influence at this historic event to advocate a position of preeminence for the late Delta bluesman". Music educator James Perone also saw that the event "underscored Robert Johnson's specific importance as a recording artist". In 1939, Columbia issued a final single, pairing "Preachin' Blues" with "Love in Vain". In 1942, commentary on Johnson's "Terraplane Blues" and "Last Fair Deal Gone Down" was included in The Jazz Record Book, edited by Charles Edward Smith. The authors described Johnson's vocals as "imaginative" and "thrilling" and his
