Tegan Quin and Sara Quin (born in Calgary, Alberta, Canada on September 19, 1980) are identical twins and Canadian singer-songwriters, performing as Tegan and Sara.

They initially played as Plunk in 1995, and lacked a drummer and 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 made an early breakthrough by winning Garage Warz Battle of the Bands, a local music competition in Calgary. Since then, the two have toured with Neil Young, Rufus Wainwright, Kaki King, The Pretenders, Ben Folds, The Killers, Rachael Cantu, Vivek Shraya, CAKE, Gogol Bordello, Hot Hot Heat, Ryan Adams, Veda Hille, Little Birdy, Iron On, Little Brazil, Bryan Adams, and Weezer, and they performed a show at Sarah McLachlan’s Lilith Fair. They are signed to Neil Young’s Vapor Records in Canada, and to Sire in the United States as their previous label, Sanctuary Records, is no longer releasing new music in the United States. Currently, Tegan lives in Vancouver, British Columbia and Sara lives in Montreal, Quebec.

When they were competing in Garage Warz, they were known as “Sara and Tegan” because that is how their mother registered them on the competition forms. Their first album, Under Feet Like Ours, was initially released under the name “Sara and Tegan”. While both twins are similarly involved in vocals and playing instruments, the singing of the lead melody usually goes to whichever twin wrote the particular song. The two hardly sang together in the recordings of their early records, but they started to more on their later records and when live.
