Document 2: Drug corridor: Drug corridor is the name given to various paths in the U.S., generally being coterminal with major highways and interstates, that are major highways for the flow of illicit drugs into, out of, and across the U.S. There is no definitive drug corridor, as many people claim that their city lies in a drug corridor (just as many people claim that their city is the "meth capital of the world"). Many sources, however, corroborate that the main arteries of drug flow are east–west across the U.S., North from Mexico, and South from Canada. Most of the marijuana and cocaine imported into the U.S. flows from Latin America across the U.S.–Mexican border, while many imported synthetic drugs and former designer drugs flow south from Canada.
Document 3: Bleed American: Bleed American is the fourth studio album by American rock band Jimmy Eat World. It was released on July 24, 2001 by DreamWorks Records. It was the first recording launched after signing the band a few months prior. The album was re-released as Jimmy Eat World after the September 11 attacks on New York and Washington, D.C. that took place a month after its initial release.
Document 4: Primer 55: Primer 55 is an American nu metal that is based in Louisville, Kentucky. The name originates from the combination of Primer, meaning "something that's unfinished," and 55, which refers to Interstate 55, "the road that drugs run on to get to Chicago through Memphis".
Document 5: The Young Souls: In 2013, the ensemble spent a great deal of time connecting with fans, which dramatically influenced the album. In September 2015, the group broadcast that their second studio album would be released at the end of October. On 24 September 2015, the ensemble released "New Again", which became the first single from the work. In October, the band published three singles which came from the record. "Cold Hearts", the second single, was published on 8 October. One week later, on 15 October 2015, "Bring You Home" was released as the third single from the album. On 22 October 2015, "Damage" was announced as the fourth single from the work.

The reissue was released on compact disc, vinyl, and digital formats.
Document 7: Interstate 57: Interstate 57 (I-57) is an Interstate Highway in Missouri and Illinois that parallels the old Illinois Central rail line for much of its route. It goes from Sikeston, Missouri, at Interstate 55 to Chicago, Illinois, at Interstate 94. I-57 essentially serves as a shortcut route for travelers headed between the south (Memphis, New Orleans, etc.) and Chicago, bypassing St. Louis, Missouri. Between the junction of I-55 and I-57 in Sikeston, Missouri and the junction of I-55 and I-90/94 in Chicago, I-55 travels for 436 mi , while the combination of I-57 and I-94 is only 396 mi long between the same two points. In fact, both the control cities on the overhead signs, as well as destination mileage signs, reference Memphis along southbound I-57, even as far north as its northern origin at I-94 in Chicago. Likewise, at its southern end, Chicago is the control city listed for I-57 on signs on northbound I-55 south of Sikeston, Missouri, even though I-55 also goes to Chicago.
Document 8: Introduction to Mayhem: Introduction To Mayhem is the major label debut album by the American nu metal band Primer 55. Released on January 25, 2000, it is a reissue of the band's 1999 EP "As Seen On TV".
Document 9: (The) New Release: (the) New Release is the second and final studio album by American nu metal band Primer 55. Released on August 14, 2001, the album peaked at #1 on the "Billboard" Heatseekers chart and #102 on the "Billboard" 200. It had one single, "This Life," which peaked at #37 on Mainstream Rock Tracks. This would be the band's final record with Island Records, who allegedly cut support shortly after the album's release due to the September 11 attacks.
Document 10: The Primates: The Primates were one of the original post-punk / rock bands to come out of Athens, Georgia in the mid 1980s. Their loud, fast in-your-face hedonistic style is reminiscent of West Coast bands X and The Minutemen, but peppered with a definite influence of traditional country music. The Primates consisted of Eric Sales - bass and vocals, Greg Reece - guitar and vocals, and LH Sales, Jr. - drums and vocals. Before going three-piece, early in the first years The Primates had a second rockabilly style guitarist - Mike Whigham. They at one point served as GG Allin's backing band.
Document 11: Interstate 85: Interstate 85 (I-85) is a major Interstate Highway in the Southeastern United States. Its current southern terminus is at an interchange with I-65 in Montgomery, Alabama; its northern terminus interchanges with I-95 in Petersburg, Virginia, near Richmond. It is nominally north–south, but physically mostly northeast–southwest. While most interstates that end in a "5" are cross-country routes, I-85 is mainly a regional route, serving five southeastern states. Major metropolitan areas served by I-85 include the Greater Richmond Region in Virginia, the Research Triangle, Piedmont Triad, and Metrolina regions of North Carolina, Upstate South Carolina, the Atlanta metropolitan area in Georgia, and the Montgomery metropolitan area in Alabama
Document 12: Hard to Explain: "Hard to Explain" is the first single from New York garage rock band The Strokes (their only previously released material was "The Modern Age" EP). It was released first in the UK and was later released in the US with different album artwork. (The UK version has a photo of two chairs, one red and one black, facing the camera. The chairs appear to be in a diner or restaurant of some sort.) Because this single is the first from their debut LP "Is This It", "Hard to Explain" made the anticipation for the album proper very high, and when "Is This It" did come out it was widely hailed as one of the best of the year. The B-side of this single, "New York City Cops" was omitted from the US version of the album in the wake of the September 11 attacks on the World Trade Center (the chorus to the song contains the lines "New York City cops/They ain't too smart").
Document 13: U.S. Route 51: U.S. Route 51 is a south-north United States highway that runs for 1286 mi from the western suburbs of New Orleans, Louisiana to within 100 ft of the Wisconsin–Michigan border. Much of the highway in Illinois and southern Wisconsin runs parallel to or overlaps Interstate 39 (I-39), and much of the route in several states also parallels the Illinois Central Railroad. The highway's northern terminus is between Hurley, Wisconsin, and Ironwood, Michigan, where it ends with a T interchange at US 2. Its southern terminus is Laplace, Louisiana, ending at US 61.
Document 14: ¡Viva Nueva!: Viva Nueva! is the fourth album by the Rustic Overtones, released in 2001 before their highly publicized breakup a year later. With 16 tracks, the album has the most songs of any Rustic Overtones album to date. Tommy Boy Records distributed the album after relations soured between the Rustic Overtones and major label Arista Records. The group produced a (supposedly) million-dollar record with Arista, then found themselves in trouble with the label after playing an extraordinarily hardcore set. It is said that an Arista representative was heard to admonish the group, yelling "We thought you were going to be like the Dave Matthews Band!" The group claimed that they had made no such promise, and Arista allowed them to take the record with them when they left. This album was then given to Tommy Boy for release, with the approval their fans. In December, 2009, the "Portland Phoenix" ranked "Viva Nueva!" the tenth greatest local album of the decade, saying that, "The fact that the vagaries of the music business beat them back doesn't diminish its greatness," and called it, "Maine's first real major-league rock album."
Document 15: Prayer (song): "Prayer" is a song released on August 14, 2002 by the American heavy metal band Disturbed as the first single from their second album, "Believe". It was inspired by the death of vocalist David Draiman's grandfather as well as various circumstances after the September 11 attacks, and is about a conversation between Draiman and God. Upon release, many media outlets refused to air the "Prayer" music video, citing supposed similarities between the imagery of the music video and that of the September 11 attacks. "Prayer" peaked at number-three on two United States airplay charts, "Billboard"'s Mainstream Rock Tracks and Modern Rock Tracks charts, as well as peaking at number-fifty-eight on "Billboard"'s Hot 100 and number-fourteen on the Canadian Singles Chart. "Prayer" is Disturbed's second highest charting single on the Billboard Hot 100 and their highest charting single on the Modern Rock Tracks chart, and 1 of only 2 of their songs to reach the top 5 on the chart (the other being "Inside the Fire", which peaked at No. 4).
