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.
It must be something in the way you walk
It must be something in the way you talk
I'm not sure just yet
It must be something in the way you dream
You just go home
And the thirteen days in between you and i
This is me before i fall apart
This is me before i come undone
I've been tired for days and days
I've been tired for days and days
Wishing that i had a fortune - don't
All the beauty and i say stop
Well, won't you be mine
It must be something in the way you taste
Your lips are magic sauce
And i say stop
Well, won't you be mine
This is me before i fall apart
This is me before i come undone
I've been tired for days and days
I've been tired for days and days
Well, it could have been a month or
It could have been a year but i
I gave up long before
Long before you cared
Her art inspired me to
To do my best and
To paint my music like
Like i saw it best and
She says i grew up well, well
Well i grew up strong
'cause no one's got my back
No one's gonna write me my songs
It could have been a month or
It could have been a year but i
I gave up long before
'cause i've been tired for days and days
I've been tired for days and days and days
I've been tired for days and days and days
Well, i've been tired for days and days and days
It could have been a month or
It could have been a year but i
I gave up long before
Long before you cared
Her art inspired me to
To do my best and
To paint my music like
Like i saw it best and
She says i grew up well, well
Well i grew up strong
'cause no one's got my back
No one's gonna write me my songs
It could have been a month or
It could have been a year but i
I gave up long before
'cause i've been tired for days and days
Well, i've been tired for days and days and days
Well, i've been tired for days and days and days
