Bob Dylan, Performing Artist is a series of three books written by music critic Paul Williams concerning the music of American singer-songwriter Bob Dylan.
 Unlike many other books about Dylan, these are not biographical but focus primarily on the performances delivered at various concerts over a period of almost forty years.
 The performances Williams analyzes were either personally attended or reviewed from audio-tapes (and sometimes from videotapes).
 In an interview published in "Isis" magazine's August 1990 issue, Williams told interviewer Derek Barker, "I didn't want to write about the person, I wanted to write about what this person has created, his art, his music."
 "Bob Dylan, Performing Artist" is considered one of the leading critical analyses of Dylan's songs and performances.
Bob Dylan ( ; born Robert Allen Zimmerman, May 24, 1941) is an American singer, songwriter, musician, painter, and writer.
 He has been influential in popular music and culture for more than five decades.
 Much of his most celebrated work dates from the 1960s, when he became a reluctant "voice of a generation" with songs such as "Blowin' in the Wind" and "The Times They Are a-Changin'", which became anthems for the Civil Rights Movement and anti-war movement.
 Leaving behind his initial base in the American folk music revival, his six-minute single "Like a Rolling Stone", recorded in 1965, enlarged the range of popular music.
The Freewheelin' Bob Dylan is the second studio album by American singer-songwriter Bob Dylan, released on May 27, 1963 by Columbia Records.
 Whereas his self-titled debut album "Bob Dylan" had contained only two original songs, "Freewheelin' " represented the beginning of Dylan's writing contemporary words to traditional melodies.
 Eleven of the thirteen songs on the album are Dylan's original compositions.
 The album opens with "Blowin' in the Wind", which became an anthem of the 1960s, and an international hit for folk trio Peter, Paul & Mary soon after the release of "Freewheelin' ".
 The album featured several other songs which came to be regarded as among Dylan's best compositions and classics of the 1960s folk scene: "Girl from the North Country", "Masters of War", "A Hard Rain's a-Gonna Fall" and "Don't Think Twice, It's All Right".
The Bob Dylan World Tour 1966 was a concert tour undertaken by American musician Bob Dylan, from February to May 1966.
 Dylan's 1966 World Tour was notable as the first tour--actually a continuation of his late 1965 U.S. tour--where Dylan employed an electric band backing him, following his "going electric" at the 1965 Newport Folk Festival.
 The musicians Dylan employed as his backing band were known as The Hawks; they subsequently became famous as The Band.
 The 1966 tour was filmed by director D. A. Pennebaker.
 Pennebaker's footage was edited by Dylan and Howard Alk to produce a little-seen film, "Eat the Document", an anarchic account of the tour.
 Drummer Mickey Jones also filmed the tour with an 8mm home movie camera.
 Many of the 1966 tour concerts were recorded by Columbia Records.
 These recordings produced two official albums, the so-called and in 2016, "The Real Royal Albert Hall Concert," as well as The 1966 Live Recordings, a 36 CD box set of every recorded concert from the 1966 tour.
 There have also many unofficial bootleg recordings of the tour.
Robert Shelton, born Robert Shapiro (June 28, 1926, Chicago, Illinois, United States – December 11, 1995, Brighton, England) was a music and film critic.
 Shelton was perhaps most notable for the way in which he helped to launch the career of a then unknown 20-year-old folk singer named Bob Dylan.
 In 1961, Dylan was performing at Gerdes Folk City in the West Village, one of the best-known folk venues in New York, opening for a bluegrass act called the Greenbriar Boys.
 Shelton's positive review, in "The New York Times", brought crucial publicity to Dylan, and led to a Columbia recording contract.
 Shelton had previously noted Dylan in a review for the New York Times of WRVR's live twelve-hour Hootenanny, July 29th, 1961.
 “Among the newer promising talents deserving mention are a 20-year-old latter-day Guthrie disciple named Bob Dylan, with a curiously arresting mumbling, country-steeped manner".
 This was Dylan's first live radio performance.
Philip Pullman CBE, FRSL (born 19 October 1946) is an English novelist.
 He is the author of several best-selling books, most notably the fantasy trilogy "His Dark Materials" and the fictionalised biography of Jesus, "The Good Man Jesus and the Scoundrel Christ".
 In 2008, "The Times" named Pullman one of the "50 greatest British writers since 1945".
 In a 2004 poll for the BBC, Pullman was named the eleventh most influential person in British culture.
No Direction Home: Bob Dylan is a 2005 documentary film by Martin Scorsese that traces the life of Bob Dylan, and his impact on 20th-century American popular music and culture.
 The film focuses on the period between Dylan's arrival in New York in January 1961 and his "retirement" from touring following his motorcycle accident in July 1966.
 This period encapsulates Dylan's rise to fame as a folk singer and songwriter, and the controversy surrounding his move to a rock style of music.
 The title is taken from a lyric of Dylan's 1965 hit single, "Like a Rolling Stone".
By 1965, Bob Dylan had achieved the status of leading songwriter of the American folk music revival.
 The response to his albums "The Freewheelin' Bob Dylan" and "The Times They Are a-Changin'" led to him being labelled as the "spokesman of a generation" by the media.
 In March 1965, Dylan released his fifth album, "Bringing It All Back Home".
 Side One featured Dylan backed by an electric band.
 Side Two featured Dylan accompanying himself on acoustic guitar.
 On July 20, 1965, Dylan released his single "Like a Rolling Stone", featuring a rock sound.
 On July 25, 1965, Dylan performed his first electric concert at the Newport Folk Festival, joined by guitarist Mike Bloomfield and Barry Goldberg of the Electric Flag.
 Some sections of the audience booed Dylan's performance.
 Leading members of the folk movement, including Irwin Silber and Ewan MacColl, criticized Dylan for moving away from political songwriting and for performing with an electric band.
Bob Dylan's Greatest Hits Vol.
 II, also known as More Bob Dylan Greatest Hits, is the second compilation album by American singer-songwriter Bob Dylan, released on November 17, 1971 by Columbia Records.
 With Dylan not expected to release any new material for an extended period of time, CBS Records president Clive Davis proposed issuing a double LP compilation of older material.
 Dylan agreed, compiling it himself and suggesting that the package include a full side of unreleased tracks from his archives.
 After submitting a set of excerpts from "The Basement Tapes" that Davis found unsatisfactory, Dylan returned to the studio in September 1971 to recut several "Basement" songs, with Happy Traum providing backup.
The Bob Dylan World Tour 1978 was a concert tour by American singer-songwriter Bob Dylan.
 In 1978, Dylan embarked on a year-long world tour, performing 114 shows in Japan, the Far East, Europe and the US, to a total audience of two million people.
 For the tour, Dylan assembled an eight piece band, and was also accompanied by three backing singers.
 When Dylan brought the tour to the United States in September 1978, he was dismayed the press described the look and sound of the show as a 'Las Vegas Tour'.
 The 1978 tour grossed more than $20 million, and Dylan acknowledged to the Los Angeles Times that he had some debts to pay off because "I had a couple of bad years.
 I put a lot of money into the movie, built a big house ... and it costs a lot to get divorced in California."
 It was during the later stages of this tour that Dylan experienced a "born-again" conversion to Christianity, which would become the overriding thematic preoccupation in his music for the next couple of years, such as on the albums "Slow Train Coming (1979) and "Saved" (1980).
