Question:
Michael John Kells Fleetwood was born in Redruth, second child to John Joseph Kells Fleetwood and Bridget Maureen (nee Brereton) Fleetwood. His elder sister Susan Fleetwood, who died of cancer in 1995, became an actress. In early childhood Fleetwood and his family followed his father, a Royal Air Force fighter pilot, to Egypt. After about six years, they moved to Norway where his father was posted on a NATO deployment.
Fleetwood was a self-taught drummer from his early childhood, after moving from a lacklustre academic performance at school to a love of music encouraged by his family, who bought him his first drum kit. His first years were heavily influenced by Tony Meehan and the Everly Brothers, and during his formative years in London during the late 1960s, Green helped Fleetwood through bouts of "rhythmic dyslexia" during live performances when Fleetwood panicked and lost the beat. He often sang filled pauses along to songs to help keep the beat. Green also instilled in Fleetwood an ability to follow and predict the lead guitarist, enabling him to meet the guitar with the drum rhythm as well as allowing him to know a good guitarist when he saw one - which would in part lead him later in his career to select Lindsey Buckingham.  Bob Brunning recalled from his early involvement with Fleetwood Mac that Fleetwood was "very open to playing with different people as long as he didn't have to change his style. He was, and is, a completely straightforward drummer, and it works with a lot of different styles. I don't s'pose [sic] he's played a traditional drum solo in his life!" Biographer Carroll highlights this ability as integral to the success of Fleetwood Mac, arguing that Fleetwood was not a virtuoso, but his disciplined and in-distractable manner of play allowed him to hold together a band of strong leading personalities without impinging upon their expression.  Caillat, in contrast, cites Fleetwood as "still one of the most amazing drummers I've ever met. He had his rack of tom drums arranged back to front. Most drummers place them from high to low (in pitch) from their left to right, but Mick chose to place his mid, high, low. I think perhaps this helped him develop his unique style. He hit his drums very hard, except for his kick drum. For some reason, when he played his high hat, it distracted him. He would keep perfect beat with his kick, but he played it so softly that we could hear his mouth noises through his kick mic."

Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.
Following the success of Hell Awaits, Slayer was offered a recording contract with Russell Simmons and Rick Rubin's newly founded Def Jam Records, a largely hip hop-based label. The band accepted and with an experienced producer and major label recording budget, the band underwent a sonic makeover for their third album Reign in Blood resulting in shorter, faster songs with clearer production. Gone were the complex arrangements and long songs featured on Hell Awaits, ditched in favor of stripped down, hardcore punk influenced song structures.  Def Jam's distributor, Columbia Records, refused to release the album due to the song "Angel of Death" which detailed Holocaust concentration camps and the human experiments conducted by Nazi physician Josef Mengele. The album was distributed by Geffen Records on October 7, 1986. However, due to the controversy, Reign in Blood did not appear on Geffen Records' release schedule. Although the album received virtually no radio airplay, it became the band's first to enter the Billboard 200, debuting at number 94, and the band's first album certified gold in the United States.  In October 1986, Slayer embarked on the Reign in Pain world tour, with Overkill in the US, and Malice in Europe. The band was added as the opening act on W.A.S.P.'s US tour, but just one month in, drummer Lombardo left the band: "I wasn't making any money. I figured if we were gonna be doing this professionally, on a major label, I wanted my rent and utilities paid." To continue with the tour, Slayer enlisted Tony Scaglione of Whiplash. However, Lombardo was convinced by his wife to return in 1987. At the insistence of Rubin, Slayer recorded a cover version of Iron Butterfly's "In-A-Gadda-Da-Vida" for the film Less Than Zero. Although the band was not happy with the final product, Hanneman deeming it "a poor representation of Slayer" and King labeling it "a hunk of shit," it was one of their first songs to garner radio airplay.

How did the band respond to this departure?
