Background: No Doubt is an American ska band from Anaheim, California, that formed in 1986. Since 1994, the group has consisted of vocalist Gwen Stefani, bassist and keyboardist Tony Kanal, guitarist and keyboardist Tom Dumont, and drummer Adrian Young. Since the mid-1990s in live performances and the studio, they have been supported by keyboardist and trombonist Gabrial McNair and keyboardist and trumpeter Stephen Bradley. The ska sound of their song, "Trapped in a Box" (1992), that was featured on their first album
Context: Eric Stefani and John Spence met at a Dairy Queen and had talked about getting a group together to play music. Eric got a keyboard and gathered some players together to practice. The practice included Eric Stefani (keyboards), Gwen Stefani (backing vocals), John Spence (lead vocals), Jerry McMahon (guitar), Chris Leal (bass), Chris Webb (drums), Gabriel Gonzalez & Alan Meade (trumpet) and Tony Meade (saxophone). They practiced in Eric's parents' garage. Tony Kanal went to one of the band's early shows and soon joined the band as its bassist. After initially rejecting her advances, he began dating Gwen, but they kept their relationship secret for a year, feeling that it was an unspoken rule that no one in the band dates her. Paul Caseley (trombone) also joined the band in 1987. Eric Carpenter (saxophone) joined the horn section soon after. In December 1987, Spence committed suicide several days before the band was to play a gig at The Roxy Theatre for record industry employees. No Doubt disbanded but decided to regroup after several weeks with Alan Meade taking over vocals. When Meade left the band, Gwen replaced him as lead singer, and No Doubt continued to develop a live following in California. In early 1988, Tom Dumont left Rising, a heavy metal band of which he was a member with his sister, stating that local metal bands "were into drinking, wearing Spandex" but that he wanted to focus on music. He joined No Doubt and replaced Jerry McMahon as the band's guitarist. Adrian Young replaced Chris Webb as the drummer the following year. During this time period, No Doubt played gigs at local colleges, Fender's Grand Ballroom, The Whisky, The Roxy, many shows with The Untouchables, Fishbone, and a show with the Red Hot Chili Peppers at Cal State Long Beach. Caseley left No Doubt in July 1989 for the US Navy Band.

Background: Richard "Red" Skelton (July 18, 1913 - September 17, 1997) was an American comedy entertainer. He was best known for his national radio and television acts between 1937 and 1971, and as host of the television program The Red Skelton Show. He has stars on the Hollywood Walk of Fame for his work in radio and television, and also appeared in burlesque, vaudeville, films, nightclubs, and casinos, all while he pursued an entirely separate career as an artist. Skelton began developing his comedic and pantomime skills from the age of 10, when he became part of a traveling medicine show.
Context: Performing the "Doughnut Dunkers" routine led to Skelton's first appearance on Rudy Vallee's The Fleischmann's Yeast Hour on August 12, 1937. Vallee's program had a talent show segment and those who were searching for stardom were eager to be heard on it. Vallee also booked veteran comic and fellow Indiana native Joe Cook to appear as a guest with Skelton. The two Hoosiers proceeded to trade jokes about their home towns, with Skelton contending to Cook, an Evansville native, that the city was a suburb of Vincennes. The show received enough fan mail after the performance to invite both comedians back two weeks after Skelton's initial appearance and again in November of that year. On October 1, 1938, Skelton replaced Red Foley as the host of Avalon Time on NBC; Edna also joined the show's cast, under her maiden name. She developed a system for working with the show's writers: selecting material from them, adding her own and filing the unused bits and lines for future use; the Skeltons worked on Avalon Time until late 1939. Skelton's work in films led to a new regular radio show offer; between films, he promoted himself and MGM by appearing without charge at Los Angeles area banquets. A radio advertising agent was a guest at one of his banquet performances and recommended Skelton to one of his clients. Skelton went on the air with his own radio show, The Raleigh Cigarette Program, on October 7, 1941. The bandleader for the show was Ozzie Nelson; his wife, Harriet, who worked under her maiden name of Hilliard, was the show's vocalist and also worked with Skelton in skits.

Background: A disc jockey, often abbreviated as DJ, is a person who plays existing recorded music for a live audience. Most common types of DJs include radio DJ, club DJ who performs at a nightclub or music festival, and turntablist who uses record players, usually turntables, to manipulate sounds on phonograph records. Originally, the "disc" in "disc jockey" referred to gramophone records, but now "DJ" is used as an all-encompassing term to describe someone who mixes recorded music from any source, including cassettes, CDs, or digital audio files on a CDJ or laptop. The title "DJ" is commonly used by DJs in front of their real names or adopted pseudonyms or stage names.
Context: Several techniques are used by DJs as a means to better mix and blend recorded music. These techniques primarily include the cueing, equalization and audio mixing of two or more sound sources. The complexity and frequency of special techniques depends largely on the setting in which a DJ is working. Radio DJs are less likely to focus on advanced music-mixing procedures than club DJs, who rely on a smooth transition between songs using a range of techniques. However, some radio DJs are experienced club DJs, so they use the same sophisticated mixing techniques. Club DJ turntable techniques include beatmatching, phrasing and slip-cueing to preserve energy on a dance floor. Turntablism embodies the art of cutting, beat juggling, scratching, needle drops, phase shifting, back spinning and more to perform the transitions and overdubs of samples in a more creative manner (although turntablism is often considered a use of the turntable as a musical instrument rather than a tool for blending recorded music). Professional DJs may use harmonic mixing to choose songs that are in compatible musical keys. Recent advances in technology in both DJ hardware and software can provide assisted or automatic completion of some traditional DJ techniques and skills. Examples include phrasing and beatmatching, which can be partially or completely automated by utilizing DJ software that performs automatic synchronization of sound recordings, a feature commonly labelled "sync". Most DJ mixers now include a beat-counter which analyzes the tempo of an incoming sound source and displays its tempo in beats per minute (BPM), which may assist with beatmatching analog sound sources. In the past, being a DJ has largely been a self-taught craft but with the complexities of new technologies and the convergence with music production methods, there are a growing number of schools and organizations that offer instruction on the techniques.
