Van der Graaf Generator are an English progressive rock band, formed in 1967 in Manchester by singer-songwriters Peter Hammill and Chris Judge Smith and the first act signed by Charisma Records. They did not experience much commercial success in the UK, but became popular in Italy during the 1970s. In 2005 the band reformed. The band formed at Manchester University, but settled in London where they signed with Charisma.
Though the group have generally been commercially unsuccessful outside of early 1970s Italy, they have inspired several notable musicians, including Rush, John Lydon, Marc Almond, Graham Coxon, Luca Prodan, Mark E. Smith, John Frusciante, Bruce Dickinson and Julian Cope. Dickinson, who has been a fan of the band since he saw them at Oundle School aged 13, said that Hammill was one of his childhood heroes. Coxon is particularly fond of "House with No Door" from H to He (1970), saying the track is "extremely beautiful, with Jackson's truly lovely sax-and-flute instrumental section." Almond recalled hearing "Killer" for the first time saying, "I'd never heard anything like it before. It wasn't just Peter's snarling operatic vocal, it was the mix of instruments ... I became an instant fan." Mentioning their reputation as something of an acquired taste, Lydon said, "There's a few Van Der Graaf things I like, but I'm not going to recommend anything to anyone. It might not be for them. Music doesn't come with a set of guidelines." Although generally categorised as a progressive rock group, Cope is keen to distance the band from that movement, stating "Their music was like some Brechtian bar band - the opposite of prog rock, really". Nevertheless, the band have been acknowledged as an influence on the neo-progressive rock subgenre which emerged in the 1980s and featured Marillion as its most successful band. Marillion singer Fish thought highly of Hammill and invited him to be the support on the band's early tours. The Canadian new wave band Men Without Hats have a song titled "The Van der Graaf Generator Blues" on their 1991 album Sideways.

Stanley Kirk Burrell (born March 30, 1962), better known by his stage name MC Hammer (or simply Hammer), is an American hip hop recording artist, dancer, record producer and entrepreneur. He had his greatest commercial success and popularity from the late 1980s, until the early 1990s. Remembered for his rapid rise to fame, Hammer is known for hit records (such as "U Can't Touch This" and "2 Legit 2 Quit"), flashy dance movements, choreography and eponymous Hammer pants. A multi-award winner, M.C. Hammer is considered a "forefather/pioneer" and innovator of pop rap (incorporating elements of freestyle music), and is the first hip hop artist to achieve diamond status for an album.
Before Hammer's successful music career (with his mainstream popularity lasting approximately between 1988 and 1998) and his "rags-to-riches-to-rags-and-back saga", Burrell formed a Christian rap music group with CCM's Jon Gibson (or "J.G.") called Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as K.B. and then eventually M.C. Hammer once it was produced), was later released on Gibson's album Change of Heart (1988). This was Contemporary Christian music's first rap hit ever. Burrell also produced "Son of the King" at that time, releasing it on his debut album. "Son of the King" showed up on Hammer's debut album Feel My Power (1987), as well as the re-released version Let's Get It Started (1988). With exception to later remixes of early releases, Hammer produced and recorded many rap songs that were never made public, yet are now available on the Internet. Via his record labels such as Bust It Records, Oaktown Records and FullBlast, Hammer has introduced, signed and produced new talent including Oaktown's 3.5.7, Ho Frat Hoo!, the vocal quintet Special Generation, Analise, James Greer, One Cause One Effect, B Angie B, The Stooge Playaz, DASIT (as seen on ego trip's The (White) Rapper Show), Teabag, Common Unity, Geeman and Pleasure Ellis; both collaborating with him and producing music of their own during his career. At about the age of 12, Oakland native Keyshia Cole recorded with Hammer and sought career advice from him.

What label produced his music?
Holy Ghost Boys.
