Problem: Background: Avenged Sevenfold (sometimes abbreviated as A7X) is an American heavy metal band from Huntington Beach, California, formed in 1999. The band's current lineup consists of lead vocalist M. Shadows, rhythm guitarist and backing vocalist Zacky Vengeance, lead guitarist and backing vocalist Synyster Gates, bassist and backing vocalist Johnny Christ, and drummer Brooks Wackerman. Avenged Sevenfold is known for its diverse rock sound and dramatic imagery in album covers and merchandise. Avenged Sevenfold emerged with a metalcore sound on the band's debut Sounding the Seventh Trumpet and continued this sound through their second album Waking the Fallen.
Context: The band's influences include Guns N' Roses, Iron Maiden, Megadeth, Pantera, Bad Religion, Dream Theater, Motorhead, Metallica, Black Sabbath, Led Zeppelin, The Rolling Stones, In Flames, At the Gates, Helloween, Queensryche, System of a Down, AC/DC, NOFX, Alice in Chains, Black Flag, Corrosion of Conformity, Suicidal Tendencies, Misfits, Slayer, The Vandals, Soundgarden, Rage Against the Machine, Korn, Slipknot, Deftones, Beastie Boys, Biohazard, Type O Negative, Anthrax and AFI.  The band has been categorized under many genres of heavy music. Mainly categorized as heavy metal, hard rock, progressive metal and metalcore, Avenged Sevenfold's music has evolved over most of the band's career. At first, the band's debut album Sounding the Seventh Trumpet consisted almost entirely of a metalcore sound; however, there were several deviations from this genre, most notably in "Streets", which shows a punk rock style, and "Warmness on the Soul", which is a piano ballad. On Waking the Fallen, the band displayed a metalcore style once more, but added more clean singing and leaned a bit more towards metal and bit less close to hardcore. In the band's DVD All Excess, producer Andrew Murdock explained this transition: "When I met the band after Sounding the Seventh Trumpet had come out before they had recorded Waking the Fallen, M. Shadows said to me 'This record is screaming. The record we want to make is going to be half-screaming half-singing. I don't want to scream anymore. And the record after that is going to be all singing'."  On City of Evil, Avenged Sevenfold's third album, the band chose to abandon the metalcore genre, using a more hard rock and heavy metal style. Avenged Sevenfold's self-titled album, however, has some experiments with other music genres than that from City of Evil, most notably in "Dear God", which shows a country style and "A Little Piece of Heaven", which is circled within the influence of Broadway show tunes, using primarily brass instruments and stringed orchestra to take over most of the role of the lead and rhythm guitar. Nightmare contains further deviations, including a piano ballad called "Fiction", progressive metal-oriented track "Save Me" and a heavy metal sound with extreme vocals and heavier instrumentation on "God Hates Us". The band's sixth studio album Hail to the King shows more of a classic metal sound and a riff-oriented approach. On their newest album The Stage, the band explores further into progressive metal, blending it with elements of thrash metal. In the past, Avenged Sevenfold has also been described as alternative metal, screamo, and pop punk metal.  The band has been criticized for "not being metal enough". Vocalist M. Shadows responded to this with, "we play music for the sake of music, not so that we can be labeled a metal band. That's like telling us we aren't punk enough. Who cares?" Avenged Sevenfold is one of the notable acts of the New Wave of American Heavy Metal.

Problem: Background: Ballmer was born in Detroit; he was the son of Beatrice Dworkin and Frederic Henry Ballmer (Fritz Hans Ballmer), a manager at the Ford Motor Company. His father was a Swiss immigrant, and his mother was Belarusian Jewish. Through his mother, Ballmer is a second cousin of actress and comedian Gilda Radner. Ballmer grew up in the affluent community of Farmington Hills, Michigan.
Context: On March 6, 2008, Seattle mayor Greg Nickels announced that a local ownership group involving Ballmer made a "game changing" commitment to invest $150 million in cash toward a proposed $300 million renovation of KeyArena and were ready to purchase the Seattle SuperSonics from the Professional Basketball Club LLC in order to keep the team in Seattle. However, this initiative failed, and the SuperSonics relocated to Oklahoma City, Oklahoma, where they now play as the Oklahoma City Thunder.  In June 2012, Ballmer was an investor in Chris R. Hansen's proposal to build a new arena in the SoDo neighborhood of Seattle and bring the SuperSonics back to Seattle. On January 9, 2013, Ballmer and Hansen led a group of investors in an attempt to purchase the Sacramento Kings from the Maloof family and relocate them to Seattle for an estimated $650 million. However, this attempt also fell through.  Following the Donald Sterling scandal in May 2014, Ballmer was the highest bidder in an attempt to purchase the Los Angeles Clippers for a reported price of $2 billion, which is the second highest bid for a sports franchise in North American sports history (after the $2.15 billion sale of the Los Angeles Dodgers in 2012). After a California court confirmed the authority of Shelly Sterling to sell the team, it was officially announced on August 12, 2014 that Ballmer would become the Los Angeles Clippers owner.  On September 25, 2014, Ballmer said he would bar the team from using Apple products such as iPads, and replace them with Microsoft products. It has been reported that he had previously also barred his household family from using iPhones.
