A vinyl compound (formula −CH=CH₂) is any organic compound that contains a vinyl group (Preferred IUPAC name ethenyl), which are derivatives of ethene, CH₂=CH₂, with one hydrogen atom replaced with some other group. An industrially important example is vinyl chloride, precursor to PVC, a plastic commonly known as "vinyl".

Vinyl groups are alkene derivatives: Primary alkenes contain vinyl groups. On a carbon skeleton, sp²-hybridized carbons or positions are often called vinylic. Allyls, acrylates and styrenics contain vinyl groups. (A styrenic crosslinker with two vinyl groups is called divinyl benzene).

The etymology of vinyl is the Latin vinum = "wine", because of its relationship with alcohol (in its original sense of ethyl alcohol).

Related to vinyl compounds are vinylidenes. Vinylidene itself, a rare species of theoretical interest, is a modified carbene with the formula CH₂=C:. Vinylidenes describe compounds containing the functional group CX₂=C. For example, 1,1-dichloroethene (CH₂=CCl₂) is called vinylidene chloride.

Richard Quitevis (born October 7, 1969) known by his stage name DJ Qbert or Qbert, is a Filipino-American Turntablist and composer.

Growing up in San Francisco's Excelsior District on Moscow Street, he graduated from Luther Burbank Middle School and in 1987 from Balboa High School. Qbert started playing with records at the age of 15, although he got his first Fisher-Price turntable as a toddler. He was influenced by the street performers and graffiti artists of the local hip hop community in the mid 1980s. It was at Balboa's school cafeteria that he went up against Mix Master Mike. The two are good friends.

Qbert started his musical career in a group called FM20 with Mix Master Mike and DJ Apollo in 1990. In New York when playing a show, Crazy Legs saw them and invited them to join the Rock Steady Crew. They accepted the offer to join the crew. Going by the name Rock Steady DJs they then proceeded to take the 1992 Disco Mix Club World DJ Championships (DMC) world title. Qbert was also one of the founding members of the band Invisibl Skratch Piklz. Although there were other turntablist crews before the Invisibl Skratch Piklz, the Skratch Piklz were the first to apply the band concept to turntablism, layering drums, basslines, and scratch solos on top of each other.

Alan Parsons (born 20 December 1948) is a British audio engineer, musician, and record producer. He was involved with the production of several significant albums, including The Beatles' Abbey Road and Let It Be, as well as Pink Floyd's The Dark Side of the Moon for which Pink Floyd credit him as an important contributor. Parsons' own group, The Alan Parsons Project, as well as his subsequent solo recordings, have also been successful commercially.

In October 1967, at age 18, Parsons went to work as an assistant engineer at Abbey Road Studios, where he earned his first credit on the LP Abbey Road. He became a regular there, engineering such projects as Paul McCartney's Wild Life and Red Rose Speedway, five albums by The Hollies, and Pink Floyd’s The Dark Side of the Moon, for which he received his first Grammy Award nomination. He was known for doing more than what would normally be considered the scope of a recording engineer’s duties.^{[citation needed]}He considered himself to be a recording director, likening his contribution to recordings to what Stanley Kubrick contributed to film.^{[citation needed]} This is apparent in his work with Al Stewart's "Year of the Cat", where Parsons added the saxophone part and transformed the original folk concept into the jazz-influenced ballad that put Al Stewart onto the charts.^{[citation needed]} It is also heard in Parsons' influence on the Hollies' "He Ain't Heavy, He's My Brother" and "The Air That I Breathe", sharp departures from their popular 1960s hits "Stay", "Just One Look", "Stop! Stop! Stop!" or "Bus Stop".^{[citation needed]} Parsons was also known to have swapped shifts during the engineering of The Dark Side of the Moon so he could work entirely on the project.^{[citation needed]}
