Bassist Joe Bouchard remembered the producer requesting his brother, drummer Albert Bouchard, play the cowbell: ``Albert thought he was crazy. But he put all this tape around a cowbell and played it. It really pulled the track together. ''However, producer David Lucas says that he played it, a claim supported by guitarist Eric Bloom.
Document 5: Houston: Centered on Post Oak Boulevard and Westheimer Road, the Uptown District boomed during the 1970s and early 1980s when a collection of mid-rise office buildings, hotels, and retail developments appeared along Interstate 610 west. Uptown became one of the most prominent instances of an edge city. The tallest building in Uptown is the 64-floor, 901-foot (275 m)-tall, Philip Johnson and John Burgee designed landmark Williams Tower (known as the Transco Tower until 1999). At the time of construction, it was believed to be the world's tallest skyscraper outside of a central business district. The new 20-story Skanska building and BBVA Compass Plaza are the newest office buildings built in Uptown after 30 years. The Uptown District is also home to buildings designed by noted architects I. M. Pei, César Pelli, and Philip Johnson. In the late 1990s and early 2000s decade, there was a mini-boom of mid-rise and high-rise residential tower construction, with several over 30 stories tall.

Document 10: North Carolina: On November 21, 1789, North Carolina became the twelfth state to ratify the Constitution. In 1840, it completed the state capitol building in Raleigh, still standing today. Most of North Carolina's slave owners and large plantations were located in the eastern portion of the state. Although North Carolina's plantation system was smaller and less cohesive than that of Virginia, Georgia, or South Carolina, significant numbers of planters were concentrated in the counties around the port cities of Wilmington and Edenton, as well as suburban planters around the cities of Raleigh, Charlotte, and Durham in the Piedmont. Planters owning large estates wielded significant political and socio-economic power in antebellum North Carolina, which was a slave society. They placed their interests above those of the generally non-slave-holding "yeoman" farmers of western North Carolina. In mid-century, the state's rural and commercial areas were connected by the construction of a 129-mile (208 km) wooden plank road, known as a "farmer's railroad", from Fayetteville in the east to Bethania (northwest of Winston-Salem).
Document 11: North Carolina: In 1860, North Carolina was a slave state, in which one-third of the population was enslaved. This was a smaller proportion than in many Southern states. The state did not vote to join the Confederacy until President Abraham Lincoln called on it to invade its sister state, South Carolina, becoming the last or second-to-last state to officially join the Confederacy. The title of "last to join the Confederacy" has been disputed; although Tennessee's informal secession on May 7, 1861, preceded North Carolina's official secession on May 20, the Tennessee legislature did not formally vote to secede until June 8, 1861.
Document 12: North Carolina: While slaveholding was slightly less concentrated than in some Southern states, according to the 1860 census, more than 330,000 people, or 33% of the population of 992,622, were enslaved African Americans. They lived and worked chiefly on plantations in the eastern Tidewater. In addition, 30,463 free people of color lived in the state. They were also concentrated in the eastern coastal plain, especially at port cities such as Wilmington and New Bern, where a variety of jobs were available. Free African Americans were allowed to vote until 1835, when the state revoked their suffrage in restrictions following the slave rebellion of 1831 led by Nat Turner. Southern slave codes criminalized willful killing of a slave in most cases.
Document 13: North Carolina: After 1800, cotton and tobacco became important export crops. The eastern half of the state, especially the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered slightly more than 10,000. The western areas were dominated by white families, especially Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence, especially in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote.
Document 14: Is There Anybody Out There?: The second half of the song is an instrumental classical guitar solo. Interestingly, it is not widely known who played it: In several interviews, David Gilmour has said that he tried to perform it, and was not satisfied with the final result (``I could play it with a leather pick but could n't play it properly fingerstyle ''). Accordingly, session musician Joe DiBlasi was brought in by Michael Kamen to play with the rest of the orchestra. He was ultimately wrongly credited as`` Ron DiBlasi'' on the album sleeve because Roger Waters only remembered that it was a three - letter name; Ron was the closest name he could remember to Joe when creating the record.
