Caillat took piano lessons as a child, but lacked significant inspiration until she turned 11 years old, when she became enthralled with Lauryn Hill's performance in Sister Act 2. She realized that she wanted to be a singer, and began taking vocal lessons, performing onstage for the first time in sixth grade. Since then she has covered the Roberta Flack song that Lauryn Hill immortalized, "Killing Me Softly", and Hill's own^{[citation needed]} "Tell Him" (an import bonus song from her solo debut album).

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.
