Freak Out!
 is the debut studio album by the American rock band the Mothers of Invention, released June 27, 1966, on Verve Records.
 Often cited as one of rock music's first concept albums, the album is a satirical expression of frontman Frank Zappa's perception of American pop culture.
 It was also one of the earliest double albums in rock music (Bob Dylan's "Blonde on Blonde" was originally scheduled to precede it by a week, but its release was delayed until more than a month later), and the first 2-record debut.
 In the UK the album was originally released as an edited single disc.
Frank Vincent Zappa (December 21, 1940 – December 4, 1993) was an American musician, composer, activist and filmmaker.
 His work was characterized by nonconformity, free-form improvisation, sound experiments, musical virtuosity, and satire of American culture.
 In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and "musique concrète" works, and produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist.
 Zappa also directed feature-length films and music videos, and designed album covers.
 Publications such as "Ultimate Classic Rock" and "The Independent" have described him as one of the most innovative and stylistically diverse rock musicians of his generation.
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".

 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.
