A hill is a landform that extends above the surrounding terrain. Hills often have a distinct summit, although in areas with scarp/dip topography a hill may refer to a particular section of flat terrain without a massive summit (e.g. Box Hill, Surrey).

The distinction between a hill and a mountain is unclear and largely subjective, but a hill is generally somewhat lower and less steep than a mountain. In the United Kingdom geographers historically regarded mountains as hills greater than 1,000 feet (300 m) above sea level, which formed the basis of the plot of the 1995 film The Englishman Who Went Up a Hill But Came Down a Mountain. In contrast, hillwalkers have tended to regard mountains as peaks 2,000 feet (610 m) above sea level: the Oxford English Dictionary also suggests a limit of 2,000 feet (610 m). This has led to Cavanal Hill in Poteau, Oklahoma, receive billing as the "World's Tallest Hill" due to its height of 1,999 feet (609 m). Mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as the Cuillin Hills and the Torridon Hills. In Wales, the distinction is more a term of land use and appearance and has nothing to do with height.

Ronald Eldon "Ron" Sexsmith (born 8 January 1964) is a Canadian singer-songwriter from St. Catharines, Ontario, currently based in Toronto. He started his own band when he was fourteen years old, and released the first recordings of his own material seven years later, in 1985. Some of the same artists who inspired Sexsmith—Paul McCartney, Elvis Costello, Ray Davies and John Hiatt—are now people whose praise he has won.

Sexsmith is the subject of a 2010 documentary, Love Shines.

Sexsmith was seventeen when he started playing at a bar, the Lion's Tavern, in his hometown. He would gain a reputation as "The One-Man Jukebox" for his aptitude for playing requests. However, four to five years of this led him to play original songs and more obscure music his audience did not favour. He decided to start writing songs after the birth of his first child, Christopher, in 1985. He moved to Toronto, formed a band called The Uncool, and released a cassette, Out of the Duff. A year later, he released There’s a Way. Next came the birth of his second child, Evelyne, in 1989. Meanwhile, he worked as a courier, and befriended Bob Wiseman whom he met at an open stage. They became friends, Wiseman produced and arranged Grand Opera Lane which was released in 1991 utilizing Ron's band consisting of Don Kerr and Steve Charles along with Wiseman regulars Sarah McElcheran (horn arrangements) and Kim Ratcliffe on electric guitar . Every Canadian label who Wiseman took it to rejected it but one year later, Todd Sullivan at Geffen Records recommended Wiseman speak with Ronnie Vance in the publishing department. Eventually on the strength of this album, and the attention garnered by the song "Speaking with the Angels", Sexsmith earned a contract which led to his self-titled album in 1995. The album received wider attention when it was praised by Elvis Costello, for whom Sexsmith later opened.

Cypress Hill is an American hip hop group from South Gate, California. Cypress Hill was the first Cuban-American/Latino hip hop group to have platinum and multi-platinum albums, selling over 18 million albums worldwide. It is one of the most well-known groups in West Coast rap and was critically acclaimed for their first two groundbreaking albums.

Senen Reyes (also known as Sen Dog) and Ulpiano Sergio Reyes (also known as Mellow Man Ace) are brothers who initially lived in South Gate, California. In 1971, their family had immigrated to the United States, settling in the Los Angeles neighborhood of South Gate. In 1988, the two brothers teamed up with Lawrence Muggerud (also known as DJ Muggs) and Louis Freese (also known as B-Real) to form a hip-hop group named DVX (Devastating Vocal Excellence). The band soon lost Mellow Man Ace to a solo career, and changed their name to Cypress Hill, after a street in South Gate.

After recording a demo in 1989, Cypress Hill signed a record deal with the major label, Columbia Records. Their self-titled first album was released in August 1991. The lead single was the double A-side "The Phuncky Feel One"/"How I Could Just Kill a Man" which received heavy airplay on urban and college radio. The other two singles released from the album were "Hand on the Pump" and "Latin Lingo", the latter of which combined English and Spanish lyrics. The success of these singles led to the album selling two million copies in the US alone. The group made their first appearance at Lollapalooza on the side stage in 1992.

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress.

She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
