Document 6: Social Distortion Summer Tour 2013: The Social Distortion Summer Tour is a concert tour that will take place in 2013. Social Distortion will kick off the tour with two appearances at the Coachella Valley Music and Arts Festival on April 14 and 21. Some of the dates on the tour are rescheduled shows from fall 2012 that were cancelled due to Hurricane Sandy.

Document 7: The Poster Boy: The Poster Boy were a Hungarian indie rock band from Budapest, Hungary. The band's line-up was Imre Poniklo from the Budapest-based indie-rock band Amber Smith, Noel R. Mayer from the alternative rock band, The Walrus, and Michael Zwecker from the Pécs-based alternative rock band Kispál És A Borz. The band members decided to form a band while chatting about the Hungarian indie scene in a bar in Budapest. In a couple of months they wrote several songs which were recorded in late 2011.
Document 8: Souled American: Souled American is an American alternative country band from Chicago, that was active mostly in the late 1980s and early 1990s. The band has its origins in Normal, a college town in central Illinois and revolves around vocalists Chris Grigoroff (also guitar) and Joe Adducci (also bass) who previously played in a band called "The Uptown Rulers". Souled American recorded four albums for Rough Trade Records, which initially stirred a modicum of critical and popular attention both in North America and Europe. In 1991 drummer Jamey Barnard left the band, and in 1992 the band released its fourth album (and last for Rough Trade),"Sonny," eight of the ten songs on which are cover tunes. After four albums, a tour with Camper Van Beethoven, and a wealth of critical acclaim (though very little commercial success — one Rough Trade employee later claimed, "The band sold less and less records with each consecutive release") Rough Trade folded and Souled American seemingly disappeared. The band re-emerged in 1994 with "Frozen" and 1997's "Notes Campfire", both released on the obscure German label Moll Tonträger. Sometime after 1996 guitarist Scott Tuma also left the band leaving the duo of Adducci and Grigoroff still intact. The remaining two members have since made sporadic appearances in their hometown and brief tours including shows in New York City, Chicago, and Ohio but new studio material has been sparse. A re-release of their first four albums on Tumult Records in 1999 brought some belated attention. In 1997, New York artist Camden Joy created a poster project called "Fifty Posters About Souled American" (the ultimate number exceeded the originally planned 50), consisting of typewritten comments and stories by various artists and musicians on the mostly forgotten band. Joy then distributed the posters around Greenwich Village.

Document 10: Tool of the Man: Tool of the Man is the fourth album by American alternative rock band Poster Children, released in 1993.

The album art consists of several optical illusions, including an afterimage of the United States flag on the front cover.
Document 11: People in Stores: People in Stores (aka PiS) was a Boston-based band from the formative punk/new wave era of the early 80s. Playing with the likes of Mission of Burma, Wild Stares, Vacuumheads, CCCP-TV, V; and The Neats, PiS performed its own unique brand of original post-punk pop music in storied clubs around Boston such as the Underground, The Rat, Storyville, and The Channel. Referred to as "the clipboard crowd" by Dan Salzman of the Maps, Art Yard and Christmas fame, PiS had a uniquely strange and intellectual approach to the crafting of a pop song. The band recorded a single, an EP and contributed to the Propeller Records compilation tape during its recording days. The band was started in 1979 and disbanded in 1983. Band members Margery Meadow and Karen Gickas, along with Thalia Zedek and Lori Green, went on to form the well-regarded, all-woman band "Dangerous Birds", while David Drucker and Seven Coursen, along with Ramona Herboldsheimer ("Wild Stares") and Andrew Joslin ("Noise Pencil"), went on to form the all-instrumental band the "Post-Moderns".

Dennis Danell was working as a producer in the Orange County area for up-and-coming punk bands and he was also in the process of recording demos for his side project. John Maurer had started his own side band as well, Foxy. Foxy had just released its debut album. On this tour, the band premiered new songs off of the Sex, Love and Rock 'n' Roll album like, "Footprints On My Ceiling", "I Wasn't Born to Follow" and "Angel's Wings" and "Road Zombie", although, "Angel's Wings" sounded almost different with different lyrics than its studio counterpart. They even played a couple songs that were rare to hear at a Social Distortion concert those days, "Hour of Darkness", "Backstreet Girl", "I Won't Run No More", "When She Begins", "King of Fools" and "Down On the World Again". This was also one of the few tours where Social Distortion did not have ANY opening acts.
