full_context: Document 1: A cappella: Barbershop music is one of several uniquely American art forms. The earliest reports of this style of a cappella music involved African Americans. The earliest documented quartets all began in barbershops. In 1938, the first formal men's barbershop organization was formed, known as the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (S.P.E.B.S.Q.S.A), and in 2004 rebranded itself and officially changed its public name to the Barbershop Harmony Society (BHS). Today the BHS has over 22,000 members in approximately 800 chapters across the United States, and the barbershop style has spread around the world with organizations in many other countries. The Barbershop Harmony Society provides a highly organized competition structure for a cappella quartets and choruses singing in the barbershop style.

Document 3: 2004 Atlantic hurricane season: There are four notables storms: Hurricane Charley, that made landfall in Florida as a Category 4 hurricane on the Saffir -- Simpson hurricane wind scale (SSHWS), causing $15.1 billion in damage in the United States alone. Later in August, Hurricane Frances struck the Bahamas and Florida, causing at least 49 deaths and $9.5 billion in damage. The most intense storm, and the one that caused the most damage, was Hurricane Ivan. It was a Category 5 hurricane that devastated multiple countries adjacent to the Caribbean Sea, before entering the Gulf of Mexico and causing catastrophic destruction on the Gulf Coast of the United States, especially Alabama and Florida. Throughout the countries it passed through, Ivan left 129 fatalities and over $23.33 billion in damage. The most significant tropical cyclone in terms of deaths was Hurricane Jeanne. In Haiti, torrential rainfall in the mountainous areas resulted in mudslides and severe flooding, causing at least 3,006 fatalities. Jeanne also struck Florida, inflicting extensive destruction. Overall, the storm caused at least $8.1 billion in damage and 3,042 deaths.
Document 4: A cappella: A cappella is gaining popularity among South Asians with the emergence of primarily Hindi-English College groups. The first South Asian a cappella group was Penn Masala, founded in 1996 at the University of Pennsylvania. Co-ed South Asian a cappella groups are also gaining in popularity. The first co-ed south Asian a cappella was Anokha, from the University of Maryland, formed in 2001. Also, Dil se, another co-ed a cappella from UC Berkeley, hosts the "Anahat" competition at the University of California, Berkeley annually. Maize Mirchi, the co-ed a cappella group from the University of Michigan hosts "Sa Re Ga Ma Pella", an annual South Asian a cappella invitational with various groups from the Midwest.
Document 5: A cappella: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
Document 6: Hurricane Maria: Hurricane Maria is regarded as being the worst natural disaster on record to affect Dominica and Puerto Rico, and is also the deadliest Atlantic hurricane since Hurricane Jeanne in 2004. The tenth-most intense Atlantic hurricane on record and the most intense tropical cyclone worldwide in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and the deadliest storm of the hyperactive 2017 Atlantic hurricane season. At its peak, the hurricane caused catastrophic damage and numerous fatalities across the northeastern Caribbean, compounding recovery efforts in the areas of the Leeward Islands already struck by Hurricane Irma. Total losses from the hurricane are estimated at upwards of $91.61 billion (2017 USD), mostly in Puerto Rico, ranking it as the third - costliest tropical cyclone on record.

Document 8: A cappella: Contemporary a cappella includes many vocal groups and bands who add vocal percussion or beatboxing to create a pop/rock/gospel sound, in some cases very similar to bands with instruments. Examples of such professional groups include Straight No Chaser, Pentatonix, The House Jacks, Rockapella, Mosaic, and M-pact. There also remains a strong a cappella presence within Christian music, as some denominations purposefully do not use instruments during worship. Examples of such groups are Take 6, Glad and Acappella. Arrangements of popular music for small a cappella ensembles typically include one voice singing the lead melody, one singing a rhythmic bass line, and the remaining voices contributing chordal or polyphonic accompaniment.
Document 9: Grammy Award for Best Contemporary Performance by a Chorus: The Grammy Award for Best Contemporary Performance by a Chorus was awarded in 1969 (as Best Contemporary Pop Performance, Chorus) and in 1970. In some years, the Grammy Award for Best Pop Performance by a Duo or Group with Vocal also included performances by a chorus.
Document 10: Hurricane Maria: Originating from a tropical wave, Maria became a tropical storm on September 16, east of the Lesser Antilles. Highly favorable environmental conditions allowed the storm to undergo explosive intensification as it approached the island arc. The hurricane reached Category 5 strength on September 18 just before making landfall on Dominica, becoming the first Category 5 hurricane on record to strike the island. After weakening slightly due to crossing Dominica, Maria achieved its peak intensity over the eastern Caribbean with maximum sustained winds of 175 mph (280 km / h) and a pressure of 908 mbar (hPa; 26.81 inHg), making it the tenth-most intense Atlantic hurricane on record. On September 20, an eyewall replacement cycle took place, weakening Maria to a high - end Category 4 hurricane by the time it struck Puerto Rico. Interaction with land further weakened the hurricane, though it regained some strength as it moved northeast of The Bahamas. Moving slowly to the north, Maria gradually degraded and weakened to a tropical storm on September 28. Embedded in the westerlies, Maria accelerated toward the east and later east - northeast over the open Atlantic, becoming extratropical on September 30 and dissipating by October 3.
Document 11: Hurricane Maria: Hurricane Maria was regarded as the worst natural disaster on record in Dominica and Puerto Rico, and caused catastrophic damage and triggered a major humanitarian crisis in the latter. The tenth-most intense Atlantic hurricane on record and the most intense tropical cyclone worldwide thus far in 2017, Maria was the thirteenth named storm, eighth consecutive hurricane, fourth major hurricane, second Category 5 hurricane, and the deadliest storm of the hyperactive 2017 Atlantic hurricane season. At its peak, the hurricane caused catastrophic damage and numerous fatalities across the northeastern Caribbean, compounding recovery efforts in the areas of the Leeward Islands already struck by Hurricane Irma just two weeks prior. Maria was the third consecutive major hurricane to threaten the Leeward Islands in two weeks, after Irma made landfall in several of the islands two weeks prior and Hurricane Jose passed dangerously close, bringing tropical storm force winds to Barbuda.
Document 12: Hurricane Irma: Hurricane Irma was an extremely powerful and catastrophic Cape Verde - type hurricane, the strongest observed in the Atlantic in terms of maximum sustained winds since Wilma and the strongest storm on record to exist in the open Atlantic region. It was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Hurricane Maria two weeks later, and is the second - costliest Caribbean hurricane on record, after Maria. The ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the 2017 Atlantic hurricane season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in parts of the northeastern Caribbean and the Florida Keys. It was also the most intense Atlantic hurricane to strike the continental United States since Katrina in 2005, the first major hurricane to make landfall in Florida since Wilma in the same year and the first category 4 hurricane to landfall in the state since Charley in 2004.

Document 14: A cappella: Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.
