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.
One time in your life
You've got the route in hand but the map is stuck
They said it's not your fault the tires are tired the camera moves
And your driver's been pulled
And I, I have always felt this
And I, I could never, I could never hear it
So I turned it up and turned it on
And turned it down
Always the volume always the words
Review the press and tell it like it is
Your life is hype, your love is hype
And I will clench my own fist
And I will always, I will always wait
There's more, there's more than blood that beats
Through my heart
My hands, my feet
Stuck between my tongue and my teeth
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
We don't know, so we only go forward
Two times in your life you will trace the edge
Sink your toes in
Review my press and tell it like it is
My life is hype, my love is hype
And I, I will clench my own fist
And I, I will always wait, I will always wait
There's more, there's more than blood that beats
Through my heart
My hands, my feet
Stuck between my tongue and my teeth
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
We don't know, so we only go forward
I'd wait up all night for you
I'd wait up all night for you
I'd wait up all night for you
I'd wait up all night for you
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
We don't know, so we only go forward
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
We don't know, so we only go forward
We don't know, so we wait for tomorrow
We don't know
We don't know, so we wait for tomorrow
We don't know, so we wait for tomorrow
