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.
Shoulders of perfection let them drag you
Straight across and tell me
Have we found perfection are we finally lost
And I'm staring from a distance
Why don't you come get a closer look
I can guarantee that lickin' the package
Ain't ever quite as good as
So they're looking for a new face with a voice to go along
I can tell you right now that ain't my style
I don't do no sing alongs
With my freedom
From the mighty sky
To the ground she said
You've got the freedom, baby
Walk out if they drag you down
They drag you down
Standin' on the edge of a crisis
We decide to raise our own voices
Consider that the sounds is our own and the fact
Our feet grow up from the ground
This is where I wanna be
This is who I wanna be
So they get my voice
But they can, they can never get my soul yes
There's a million things about me you will never know
Like they caught me on video
And yeah, they caught me on radio
Yeah, they caught me on video, radio, stereo
Freedom from the mighty sky to the ground she said
You've got the freedom, baby walk out
If you drag me down
You've got the freedom baby to walk out
If they drag you down
If they drag you
If they drag you
Standin' on the edge of a crisis
We decide to raise our own voices
Consider that the sounds is our own and the fact
Our feet grow up from the ground
Baby, this is where I wanna be
This is who I wanna be
So they get my voice
But they can they can never get my soul yes
There's a million things about me you will never know
Like they caught me on video
And yeah, they caught me on radio
Yeah, they caught me on video, radio, stereo
Freedom from the mighty sky to the ground she said
You've got the freedom, walk out
They drag you
They drag you
If they drag you, you walk out
