Tegan Rain Quin y Sara Keirsten Quin nacieron el 19 de septiembre de 1980 en Calgary, Alberta, Canadá. Desde muy temprana edad, las gemelas mostraron un interés ferviente por la música. Al crecer en una casa llena de discos y guitarras, no era raro verlas tocando o experimentando con melodías y letras desde que tenían ocho años.
Durante su adolescencia, Tegan y Sara comenzaron a escribir y grabar sus propias canciones. En 1998, con solo 18 años, ganaron una competencia de radio local cuyo premio era tiempo de estudio profesional para grabar un álbum. Este evento marcó el punto de partida de su carrera profesional y poco después, lanzaron su primer álbum "Under Feet Like Ours" de forma independiente en 1999.
En el año 2000, firmaron con el sello Vapor Records, fundado por Neil Young. Este acuerdo cimentó su camino a la fama. Su segundo álbum, "This Business of Art" (2000), fue bien recibido por la crítica y les permitió iniciar giras más extensas en Canadá y Estados Unidos, abriendo para bandas como Neil Young y The Pretenders.
Con el lanzamiento de "If It Was You" en 2002 y "So Jealous" en 2004, la dupla alcanzó una notoriedad aún mayor. "So Jealous" en particular hizo que captaran la atención del público internacional, gracias a canciones como "Walking with a Ghost", que fue versionada por la popular banda The White Stripes.
No I'm not ready for a big bad step in their direction.
No I'm not ready for downtown trash, avoid collection.
Four blocks, run and hide, don't walk alone at night.
Cityscape, city change before they die.
Four blocks, I should mention in a song
if I want to get along with change,
who doesn't want to change this?
I know you feel it too, these words get overused.
When we get up and over it and over them,
up and over it and over them.
I know you feel it too, it all seems so untrue.
When you get up and over it and over them,
oh oh hell no, oh oh hell no.
No we're not ready for a fair distribution,
just a terminal solution for...
No we're not ready for hell hell no for hell hell no.
Four days, wide awake, why slide along and say.
Girl's afraid girl will change just move away.
Four days that I mention in a song move along,
get ahead, get her hand and bring her with you.
I know you feel it too, these words get overused.
When we get up and over it and over them,
up and over it and over them.
I know you feel it too, it all seems so untrue.
When you get up and over it and over them,
oh oh hell no, oh oh hell no.
Four ways to remove all the bad that we do
from the heart and the soul of the cities sad and cold.
Four ways to collect what we say and what we save
to discard and discover a brand new way.
I know you feel it too, these words get overused.
When we get up and over it and over them,
up and over it and over them.
I know you feel it too, it all seems so untrue.
When you get up and over it and over them,
up and over it and over them.
I know you feel it too, these words get overused.
When we get up and over it and over them,
up and over it and over them.
I know you feel it too, it all seems so untrue.
When you get up and over it and over them,
oh oh hell no, oh oh hell no.
Oh oh hell no, oh oh hell no.
