Context paragraphs:
Rendezvous with Ragnarok: Rendezvous with RagNaRok is a performance film by the band Gwar coinciding with their 1995 album "RagNaRok", though the video was released in early 1997 (much of the footage was from 1996).  The bulk of the video is concert footage, with a mock interview interspersed between each song.  Additionally, three music videos - "Saddam a Go-Go," "Meat Sandwich," and "Surf of Syn" - are among the scenes.

Gas Giants (band): Gas Giants were a pop rock band from Tempe, Arizona, formed as a successor project to the Gin Blossoms.  The group was known as The Pharaohs when they formed in 1997, but changed their name after their label, A&M Records, merged with Universal Records and the band changed hands, re-signing with Interscope Records.  Eventually, the group released their album, "From Beyond the Back Burner", in 1999 on indie Atomic Pop Records.  Comic book artist Geof Darrow provided the artwork for the album.  The band featured Gin Blossoms members Robin Wilson, Phillip Rhodes and Daniel Henzerling, as well as Mickey Ferrel, who was previously in the band Grievous Angels.  Henzerling was the drummer for the Gin Blossoms before the current drummer, Phillip Rhodes.  The band toured with Train in 2000 behind the band's only single, "Quitter".

Morogoro Jazz Band (K.Z. standing for "Kuliko Zote", Swahili for "better than the others"), was a seminal muziki wa dansi band from Morogoro, Tanzania.  The band originally played live at the clubs and bars of Morogoro and became very popular in the 1960s and 1970s, receiving considerable airplay from Tanzanian radio stations.  The leader of the band was guitarist Mbaraka Mwinshehe, who dropped out of school to join the band in 1965.  Coincidentally, the band was formed the same year Mwinsheshe was born, in 1944.  The original lineup of the band featured Makala Kindamile, Joseph Thomas, Seif Ally, Daudi Ally and Shaabana Mwambe.  Salim Abdullah, who would later found Cuban Marimba Band, was also an early member of the band.

Dovetail Joint (band): Dovetail Joint was a rock band that formed in Chicago, Illinois in 1992.  The band featured guitar/vocalist Charles Gladfelter, guitarist Robert Byrne, bassist Jon Kooker, and drummer Joe Dapier.  After several years of playing locally, as well as independently releasing their self-titled album in 1995, the band started to garner interest after their song "Level on the Inside" was featured on an annual compilation disc of local radio station WKQX Q101.  Columbia Records quickly signed the band and released "001" in early 1999.  "Level" turned out to be the band's only commercial hit, and Columbia dropped the band before releasing a second album.  However, an independently released EP was released in 2002 which would turn out to be their last.

Gwar: Gwar, often styled as GWAR, is an American heavy metal band formed in Richmond, Virginia in 1984, composed of and operated by a frequently rotating line-up of musicians, artists and filmmakers collectively known as Slave Pit Inc..

International Sweethearts of Rhythm: The International Sweethearts of Rhythm was the first integrated all women's band in the United States.  During the 1940s the band featured some of the best female musicians of the day.  They played swing and jazz on a national circuit that included the Apollo Theater in New York City, the Regal Theater in Chicago, and the Howard Theater in Washington, DC.  After a performance in Chicago in 1943, the "Chicago Defender" announced the band was, "One of the hottest stage shows that ever raised the roof of the theater!"  More recently, they have been labeled "the most prominent and probably best female aggregation of the Big Band era."  During feminist movements of the 1960s and 1970s in America, the International Sweethearts of Rhythm regained a significant amount of popularity, particularly with feminist writers and musicologists who have made it their goal to change the discourse on the history of jazz to equally include both men and women musicians.  Antionette Handy, flutist, documented the story of these female musicians of color.
