Background: Allison was born December 3, 1937 in Miami, FL. He entered his first race as a senior at Archbishop Curley-Notre Dame High School in Miami. Since he was only 17, he had to have his parents' permission so he thought when his mother said ok, it was forever, but she thought it was for only one race.
Context: The 1973 National 500 was held October 7, 1973 at Charlotte Motor Speedway in Concord, North Carolina. The first three cars to cross the finish line after the scheduled 334 laps (501 miles) were driven by Cale Yarborough, Richard Petty, and Bobby Allison, in that order. Again, these facts are not disputed. What is disputed, is the legality of the first two cars' engines, recounted in Jim McLaurin's book "NASCAR'S Most Wanted", in the chapter "Fudgin' With the Rules": In the 1973 National 500 at Charlotte Motor Speedway, Allison protested that the engines in winner Cale Yarborough's and second-place Richard Petty's cars were over-sized. NASCAR inspected all three of the top finishers, and Allison's engine fit the cubic-displacement specs. Six hours after the inspections began, NASCAR technical director Bill Gazaway told the press that the results were being sent to headquarters in Daytona for a final decision. Monday afternoon NASCAR released a statement saying that, because the inspection facilities at Charlotte were inadequate, the pre-race inspection numbers would be used-when all three cars were legal and that the results would stand. Allison threatened both to quit and to sue. It was not until after a private meeting with NASCAR President Bill France, Jr., a week later that Allison was assuaged. Speculation was that Allison had been bought off. Allison wouldn't confirm or deny it, saying only that he had "received satisfactory restitution". The results were never changed. 1973 was a transition year in NASCAR. Teams could run a restrictor plate-equipped 7-liter engine or a 5.9 liter engine without restrictor plates. A decade later, Petty's over sized engine at the same race resulted in new NASCAR rules being implemented against oversized engines, including the possibility of twelve-week suspensions for the offending engine builder, driver, and car owner.

Background: Thomas Wesley Pentz (born November 10, 1978), better known by his stage name Diplo, is an American DJ, record producer, rapper and songwriter based in Los Angeles, California. He is the co-creator and lead member of the electronic dancehall music project Major Lazer, and along with producer and DJ Skrillex, part of the electronic duo Jack U. He founded and manages record company Mad Decent, as well as co-founding the non-profit organization Heads Decent. Among other jobs, he has worked as a school teacher in Philadelphia.
Context: Diplo was born on November 10, 1978, in Tupelo, Mississippi, the son of Barbara Jean (nee Cox) and Thomas Pentz. He is of German and English descent. The influence of home-grown rap played a key role in helping shape his production style. He spent the majority of his youth in Miami, where he got a taste for the characteristic Miami bass. He began attending the University of Central Florida in 1997, and then moved to Philadelphia to continue his studies at Temple University, where he first garnered attention as a DJ. After frequently running into fellow DJ Low Budget, the two began throwing parties under the Hooked on Hollertronix moniker in 2003 as a way of maintaining control of what they were able to play during DJ gigs in Philadelphia. The success of these parties allowed the two to release mixtapes, both separate and together, gathering acclaim across the country. One such mixtape, Never Scared, was named one of the New York Times top ten albums of 2003, and the Hollertronix name became synonymous with parties featuring guests like Maluca Mala, Bun B, Spank Rock, M.I.A., among others. Hollertronix's sound has been described as "disparate genres to be smashed together for maximum attention-grabbing impact" an aesthetic which takes from the "organic, cohesive, whole" aesthetic of acts such as Bun B, Lil Jon, Drama, M.I.A., Bjork, Busta Rhymes, and others. Diplo accentuated the club aesthetic of his Hollertronix music for a more reflective sound on his solo debut, Florida, which was released on the Ninja Tune imprint, Big Dada Records. The album Florida was pressed twice, first with a CD and the second with a CD and DVD. The DVD was created by System D-128, another artist who has collaborated with Diplo on some audio and video projects. Before Florida's DVD accompaniment, another DVD surfaced called Diplo: "Banned in Libya" which was released by Money Studies, the first label to release a solo project by Diplo under his original DJ name Diplodocus. It was a 45 rpm record called "Thingamajawn" for which there is also a music video System D-128 directed. Similar to the Florida DVD, "Banned in Libya" is an experimental audio and video mix of some of Diplo's original music blended with a number of other unidentified sources. His particular affinity for one genre of music called baile funk, or favela funk, would spawn a series of mixtapes (Favela on Blast, Favela Strikes Back), which served to bring the Brazilian dance music of the ghettos to the United States. It was not long before his Hooked on Hollertronix parties would provide him the success necessary to move to the next logical step and build a studio where music would become his full-time focus. With this goal in mind, Diplo built "The Mausoleum," a video studio, recording studio, record label office, gallery, and event space in Philadelphia. Since its inception, The Mausoleum has become the home to recordings by artists like Christina Aguilera, Shakira, M.I.A., Santigold, Spank Rock, Plastic Little, Blaqstarr, Paper Route Gangstaz, and hosted concerts by Glass Candy, Skream, Boys Noize, Nicos Gun, and more.
