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.
Jeff Simmons (born May 21, 1949 in Seattle, Washington) is an American rock musician best known as a former member of Frank Zappa's Mothers of Invention.
The Frank Zappa AAAFNRAAA Birthday Bundle 2008 was released as a digital download on iTunes on December 21, 2008.

 It is the second iTunes album by Frank Zappa, the first being "The Frank Zappa AAAFNRAA Birthday Bundle" (2006).
 (AAAFNRAA stands for "Anything Anytime Anywhere for No Reason At All", Zappa's motto of sorts.)
 The additional A in this release's title stands for "Again".
Barking Pumpkin Records is an independent record label based in California that specialized in mail order releases.
 The label was founded in 1981 by Frank Zappa.

 After Frank Zappa died in 1993, Barking Pumpkin continued to release his posthumous albums, and new content by Z.
The soundtrack to Frank Zappa's film "200 Motels" was released by United Artists Records in 1971 and features a combination of rock and jazz songs, orchestral music and comedic spoken dialogue.
 The album, like the film, covers a loose storyline about The Mothers of Invention going crazy in the small town Centerville, and bassist Jeff quitting the group, as did his real life counterpart, Jeff Simmons, who left the group before the film began shooting and was replaced by actor Martin Lickert for the film.
