Tegan and Sara is a band consisting of Canadian singer-songwriters, and identical twins, Tegan Rain Quin and Sara Kiersten Quin.

Tegan and Sara were born in Calgary, Alberta. They initially played as PLUNK, and lacked a drummer and bass player. In 1997, the two 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 and Sara lives in Montreal.

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"; copies are now a sought-after commodity among their fans.

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 usually do not sing together on their early albums, however, they do on their later albums and in concert.

Their fifth album, The Con, was released on July 24, 2007. It was co-produced by Chris Walla of Death Cab for Cutie. Jason McGerr of Death Cab for Cutie, Matt Sharp of The Rentals, Hunter Burgan of AFI, and Kaki King appear on the album.

Check them out live at The Murat Egyptian Room on May 8th.
