IN: Dion Francis DiMucci (born July 18, 1939), better known mononymously as Dion, is an American singer, songwriter whose work has incorporated elements of doo-wop, rock and R&B styles--and, most recently, straight blues. He was one of the most popular American rock and roll performers of the pre-British Invasion era. He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, with the Belmonts or with the Del Satins. He is best remembered for the singles "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among his other hits.

Bob and Gene Schwartz also signed Dion's friends, the Belmonts, (Carlo Mastrangelo, Fred Milano, and Angelo D'Aleo), a vocal group named for nearby Belmont Avenue, and teamed them, with Dion singing lead. The new group's breakthrough came in early 1958, when "I Wonder Why" (on their newly formed "Laurie" label) made No. 22 on the U.S. charts. Dion said of the Belmonts; "I'd give 'em sounds. I'd give 'em parts and stuff. That's what 'I Wonder Why' was about. We kind of invented this percussive rhythmic sound. If you listen to that song, everybody was doing something different. There's four guys, one guy was doing bass, I was singing lead, one guy's going 'ooh wah ooh,' and another guy's doing tenor. It was totally amazing. When I listen to it today, oftentimes I think, 'man, those kids are talented.'" Their initial hit was followed by "No One Knows" and "Don't Pity Me," which also charted the Billboard Top 100. This success won a place for Dion and the Belmonts on the ill-fated "The Winter Dance Party" tour with Buddy Holly, Ritchie Valens, the Big Bopper (J.P. Richardson), Frankie Sardo, and other performers. On February 3, 1959, after a concert stop in Clear Lake, Iowa, Holly and others decided to charter a flight to the next venue rather than travel on the tour bus. Dion was invited to accompany the group but decided that he did not want to spend $36 for the flight, as it was the same monthly rent his parents paid for his childhood apartment and he couldn't justify the indulgence. The plane crashed, killing all on board; Holly, Valens, Richardson, and the pilot Roger Peterson. Dion and the Belmonts continued on the tour, along with Frankie Sardo, while Bobby Vee, then an unknown artist, performed in Holly's place at the very next concert. Later, Jimmy Clanton, Frankie Avalon, and Fabian were added to replace the other now-deceased headliners. Dion and the Belmonts' next single, "A Teenager in Love," was released in March 1959, eventually hitting No. 5 on the U.S. pop charts and No. 28 in the UK. The group's biggest hit, "Where or When," was released in November of that year, and reached No. 3 on the U.S. charts. However, in early 1960, Dion checked into hospital for heroin addiction, a problem he had had since his mid-teens. Further single releases for the group that year were less successful. There were musical, personal and financial differences between Dion and members of the Belmonts, and in October 1960, Dion decided to quit for a solo career. By the time of their breakup, all eight Laurie releases had charted on the Hot 100.

IN: Armando Christian Perez (born January 15, 1981), known by the stage name Pitbull or Mr. Worldwide, is an American rapper. His first recorded mainstream performance was on a solo track from Lil Jon's 2002 album Kings of Crunk. In 2004, Pitbull released his debut album M.I.A.M.I. under TVT Records. It included production producers Lil Jon and Jim Jonsin.

In 2004, Pitbull released his debut album M.I.A.M.I., with the lead single being "Culo" produced by Lil Jon and the Diaz Brothers. It peaked at No. 32 on the Billboard Hot 100 chart and No. 11 on the Hot Rap Tracks chart. Other singles included "Dammit Man", "Back Up", "Toma", and "That's Nasty" (both featuring Lil Jon). He joined the Anger Management Tour, the 2000 hip-hop concert tour headlined by Eminem and 50 Cent. Pitbull also appeared on the Ying Yang Twins' single "Shake", which peaked at No.41 on the Hot 100 and No.12 on the rap chart, Adassa's chart topping single "Kamasutra" & Twista's "Hit the Floor" (#94 Hot 100, No. 20 Rap). Remix album Money Is Still a Major Issue was released in November 2005; it included new track "Everybody Get Up", a duet with hip-hop/R&B group Pretty Ricky. TVT Records, Pitbull's label at the time, and Slip-n-Slide Records disputed over the release of Welcome to the 305, an unreleased album by Slip-n-Slide that Pitbull had recorded in 2001. A Miami judge ruled that Slip-n-Slide had a legal right to release the album as it was recorded when Pitbull was a Slip-N-Slide artist, and prior to him signing with TVT Records. A U.S. District Court judge affirmed the decision further. TVT was then ordered in March 2007 to pay Slip-n-Slide $9.1 million for attempting to block the album's release to record stores and digital download entities. In 2005 Pitbull and rapper Sean 'Diddy' Combs co-founded Bad Boy Latino, a subsidiary of Combs' Bad Boy Records label. It primarily focuses on Latin hip hop, Latin soul, Latin pop and other tropical music and has offices in New York and Miami, Florida. Along with co-founding it, Perez currently heads the A&R division of the label.
