Tegan and Sara are a Canadian indie band formed in 1995 in Calgary. Composed of identical twin sisters Tegan Rain Quin and Sara Keirsten Quin (born September 19, 1980). Both Tegan and Sara play guitar and keyboard and write their songs.

Tegan and Sara Quin were born September 19, 1980 in Calgary, Alberta. They began playing guitar and writing songs at age 15. They initially played as Plunk without a drummer or bass player. In 1997, they used their school’s recording studio to record two demo albums: Who's in Your Band? and Play Day. In 1998, they won Calgary's Garage Warz competition, using the studio time they won to record their first professional demo, Yellow tape, which was followed by Orange tape and Red tape.

Two songs from Red tape appeared on their first album, Under Feet Like Ours, which they released independently in 1999 under the name "Sara and Tegan". They later changed their name to "Tegan and Sara" because it was easier to pronounce and reprinted the album using that name. They also wanted their name to stand out amongst the other 'Sara' musicians at the time such as Sarah McLachlan and Sarah Slean. Tegan was easier to remember.^{[citation needed]}Neil Young's manager signed them to Young's Vapor Records label, and they released This Business of Art through Vapor in 2000. They have toured extensively since then.

Christina María Aguilera (born December 18, 1980) is an American recording artist and actress. Aguilera first appeared on national television in 1990 as a contestant on the Star Search program, and went on to star in Disney Channel's television series The Mickey Mouse Club from 1993 to 1994. Aguilera signed to RCA Records after recording "Reflection", the theme song for the animated film Mulan (1998).

In 1999, Aguilera came to prominence following her debut album Christina Aguilera, which was a commercial success spawning three number one singles on the Billboard Hot 100—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)." Her sophomore and her debut Latin-pop album, Mi Reflejo (2000), a Christmas third studio album, My Kind of Christmas (2000), and several collaborations followed which garnered Aguilera worldwide success, though she was displeased with her lack of input in her music and image. After parting from her management, Aguilera took creative control over her fourth studio album, Stripped (2002). The album's second single, "Beautiful", was a commercial success and helped the album's commercial performance amidst controversy over Aguilera's image. Aguilera followed up Stripped with the soul, jazz and blues inspired, Back to Basics (2006), released to positive critical acclaim. The album produced three singles "Ain't No Other Man", "Hurt" and "Candyman". Four years later Aguilera released her sixth studio album, Bionic (2010), which incorporated aspects of R&B, electropop, and synthpop and was met with mixed reviews and low sales. Aguilera's seventh studio album is set to be released in 2012.
