Problem: Background: Xenomania is an English songwriting and production team founded by Brian Higgins and based in Kent, England. Formed after Higgins met Miranda Cooper, Xenomania has written and produced for renowned artists such as Cher, Kylie Minogue, Dannii Minogue, Sophie Ellis-Bextor, Pet Shop Boys, The Saturdays and the Sugababes. In particular, all but one of Girls Aloud's studio albums have been entirely written and produced by Xenomania. Sugababes' "Round Round" and Girls Aloud's "Sound of the Underground" have been credited with reshaping British pop music for the 2000s.
Context: Higgins and Xenomania were once again given free rein for Girls Aloud's third album, Chemistry. The album's second single, "Biology", was critically acclaimed, being called "the best pop single of the last decade". Despite the group's near total obscurity in the United States, the song was listed at number 245 on Pitchfork Media's "The Top 500 Tracks of the 2000s" list. It was also listed at number 23 on The Observer Music Monthly's 75 best singles of the decade. Chemistry was praised by critics upon its release. BBC Music decided that the album was "quirky, modern and dripping with attitude" and "holds no disappointments." Virgin Media gave the album five stars, saying it was "bursting [...] with invention, quirky lyrics, tongue-in-cheek sauciness and [...] appeals to grown-up pop fans and music critics as well as to the teenyboppers." In 2008, Slant Magazine said that "Chemistry is probably still their crowning glory". Xenomania worked with other British artists such as Bananarama, Texas, and Rachel Stevens. They contributed tracks to Stevens' album Come and Get It, a commercial failure that The Guardian listed among its "1000 Albums to Hear Before You Die" and hailed as "a riot, thanks to a stellar team of pop producers [...] who seem to have taken the precarious state of Stevens' career as an excuse to let their imaginations run amok". Xenomania continued their work with both Saint Etienne and Sugababes, producing the latter's UK top five single "Red Dress" (from the 2005 album Taller in More Ways), described by The Observer as "a thumping tour de force from Xenomania [...] Not unexpectedly, it flirts vivaciously with pop songwriting convention, boasting not one but two killer choruses". Xenomania also produced Totally Frank stars Frank's 2006 debut album; the group was dropped after their album failed to perform well. In 2006, Girls Aloud released their first greatest hits collection, The Sound of Girls Aloud, which featured their singles to date--all produced by Xenomania--including the new track "Something Kinda Ooooh". The song was referred to as "another head-spinningly innovative number from the Xenomania team." The Sound of Girls Aloud has been recognised by the IFPI as a million-seller. Their fourth studio album, 2007's Tangled Up, was labelled "yet another unrelenting pop masterpiece." The Times included it at number 62 on a list of the decade's best pop albums. The single "Call the Shots" was critically acclaimed, with pop music journalist Peter Robinson calling it the "greatest pop song of the 21st century." Xenomania also worked with Alesha Dixon (on the single "Knockdown"), Sophie Ellis-Bextor, and produced two songs for Sugababes' fifth studio album, Change.

Answer:

Background: Charles Henry "Chuck" Noll (January 5, 1932 - June 13, 2014) was a professional American football player, assistant coach and head coach. His sole head coaching position was for the Pittsburgh Steelers of the National Football League (NFL) from 1969 to 1991. When Noll retired after 23 years, only three other head coaches in NFL history had longer tenures with one team. After a six-year playing career that included two NFL Championships as a member of his hometown Cleveland Browns, and several years as an assistant coach with various teams, in 1969 Noll took the helm of the then moribund Steelers (which had played in only one post-season game in its previous 36 years, a 21-0 loss), and turned it into a perennial contender.
Context: Noll's legacy includes providing opportunities for African Americans. Under Noll, Joe Gilliam became the league's first African American starting quarterback just a few seasons after the AFL started Marlin Briscoe, and James Harris (Gilliam started ahead of Terry Bradshaw briefly during the 1974 season). In 1975, Franco Harris became the first African American to win the Super Bowl MVP award. During the 1980s, Tony Dungy (who briefly played under Noll in the late 1970s) got his start as an NFL assistant coach, initially as the Steelers' Defensive Backs Coach, and later he became the first African-American Coordinator in the NFL. Noll strongly promoted Dungy as a well-qualified head coaching candidate, but it did not happen for Dungy with the Steelers when Noll retired after the 1991 season. However Dungy did become head coach of the Tampa Bay Buccaneers and later became the first African American coach to win a Super Bowl (XLI) with the Indianapolis Colts. On August 2, 2007, the field at St. Vincent College in Latrobe, Pennsylvania was dedicated and renamed Chuck Noll Field in honor of the former coach. For more than 40 years the Steelers have held their summer camp at St. Vincent College, as it was Noll's idea to take the team away from the distractions in the city to prepare for the season each year. Chuck Noll was honored on October 7, 2007 at Heinz Field during the pre-game ceremonies. On September 30, 2011, Pittsburgh honored Noll by naming a new street after him. Chuck Noll Way connects North Shore Drive to West General Robinson St. The street runs along Stage AE, on the North Shore of Pittsburgh.
