Problem: Daron Vartan Malakian (Armenian: Taron/Taron Vardan Malak'ean, born July 18, 1975) is an Armenian-American singer-songwriter, multi-instrumentalist, and record producer. He is best known as the guitarist, songwriter and second vocalist of the heavy metal band System of a Down and as the lead vocalist, lead guitarist and songwriter of the band Scars on Broadway. Daron Malakian is known for his distinctive playing and is ranked 40th in Loudwire's list of Top 50 Hard Rock + Metal Guitarists Of All Time and #11 in MusicRadar's poll, The 20 Greatest Metal Guitarists Ever.

In 2003, Daron Malakian (lead guitar and vocals), Greg Kelso (rhythm guitar), Casey Chaos (vocals), and Zach Hill (drums) recorded a demo tape entitled Ghetto Blaster Rehearsals, credited to the name Scars on Broadway. However, in 2007, an official letter appeared on the band's website that stated that these tracks are not in any way affiliated with Malakian's later project Scars on Broadway. Incidentally, these demo sessions produced "B.Y.O.B.", which would be a major hit for System of a Down in 2005. Following System's hiatus, Malakian announced his latest project - Scars on Broadway - a band which would include System of a Down bassist, Shavo Odadjian, and himself. Ultimately, Odadjian was not involved with the band, and instead System of a Down drummer, John Dolmayan became a member. After Malakian and Dolmayan experimented with different musicians (for a period of nine months in 2007 - 2008) the band took form and forged its sound in intense rehearsals and recording sessions (under Malakian's direction at his home studio and Sunset Sound) with musicians Danny Shamoun on keyboards, Dominic Cifarelli on bass, and Franky Perez on guitar and backing vocals for live performances (in the studio Malakian played nearly all the instruments with the exception of drums which were played by Dolmayan and some overdubs provided by the other members). The group released an eponymous album in 2008, which featured the hit single "They Say" (written by Malakian). However, shortly before the tour supporting the album, Malakian cancelled all scheduled concert and TV appearances, blaming a lack of enthusiasm and that his "heart wasn't into touring." This sudden cancellation prompted speculation and rumors that the band had broken up. It was the last that would be heard of Malakian for more than a year. In August 2009, Scars on Broadway, minus Malakian, traveled to Iraq for a USO tour across the U.S. army bases. Their setlist consisted of covers as well as a few Scars songs. Guitarist/vocalist Franky Perez stated on his Twitter that "the Scars tunes sound amazing but they're not the same without D..." He also stated before they left that Malakian had given them his blessing. In 2009 Franky Perez mentioned on his Twitter that he and the D-Man (Malakian) were going into studio to jam, this was the first news people have heard about Malakian's whereabouts for about a year. On May 2, 2010, Malakian reunited with Scars on Broadway at the Troubadour in West Hollywood. It was the first time he had performed with the band since October 2008. The group played songs from their album as well as new songs. Odadjian performed with the band for two songs, playing guitar. On February 24, 2012, System of a Down announced that the Scars on Broadway website is back online featuring a preview of a new song called "Guns Are Loaded".

Problem: A big band is a type of musical ensemble that usually consists of ten or more musicians with four sections: saxophones, trumpets, trombones, and a rhythm section. Big bands originated during the early 1910s and dominated jazz in the early 1940s when swing was most popular. The term "big band" is also used to describe a genre of music. One problem with this usage is that it overlooks the variety of music played by these bands.

Before 1914, social dance in America was dominated by steps such as the waltz and polka. As jazz migrated from its New Orleans origin to Chicago and New York City, energetic, suggestive dances traveled with it. During the next decades, ballrooms filled with people doing the jitterbug and Lindy Hop. The dance duo Vernon and Irene Castle popularized the foxtrot while accompanied by the orchestra of James Reese Europe. One of the first bands to accompany the new rhythms was led by a drummer, Art Hickman, in San Francisco in 1916. Hickman's arranger, Ferde Grofe, wrote arrangements in which he divided the jazz orchestra into sections that combined in various ways. This intermingling of sections became a defining characteristic of big bands. In 1919, Paul Whiteman hired Grofe to use similar techniques for his band. Whiteman was educated in classical music, and he called his new band's music symphonic jazz. The methods of dance bands marked a step away from New Orleans jazz. With the exception of Jelly Roll Morton, who continued playing in the New Orleans style, bandleaders paid attention to the demand for dance music and created their own big bands. They incorporated elements of Broadway, Tin Pan Alley, ragtime, and vaudeville. Duke Ellington led his band at the Cotton Club in Harlem. Fletcher Henderson's career started when he was persuaded to audition for a job at Club Alabam in New York City, which eventually turned into a job as bandleader at the Roseland Ballroom. At these venues, which themselves gained notoriety, bandleaders and arrangers played a greater role than they had before. Hickman relied on Ferde Grofe, Whiteman on Bill Challis. Henderson and arranger Don Redman followed the template of King Oliver, but as the 1920s progressed they moved away from the New Orleans format and transformed jazz. They were assisted by a band full of talent: Coleman Hawkins on tenor saxophone, Louis Armstrong on cornet, and multi-instrumentalist Benny Carter, whose career lasted into the 1990s.
