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.
We were so high we thought we'd definitely die
'Cause we were dead already, dying
Endless nights took on my whole life
Or so I thought
It turns out all your friends
They were just mean, dressed up
So, come on kids eat those pills
You got your whole life to lose
We've got so many friends
That wear their feet too big for their shoes
We've got cities to visit
We've got trees we've yet to live in
And so get yourself on top of me
Before I'm gone, gone, gone
We were so young
I thought that acting old
Would give me all your love
Give me all you?ve got
So, come on kids eat those pills
You've got your whole life to lose
And we've got so many friends
That wear their feet too big for their shoes
We've got cities to visit
We've got trees we've yet to live in
So get yourself on top of me
Before I'm gone, gone, gone
And all night long
On your front lawn
you'd build me a neon village
And you said bring on new diseases
If they're good for you
Then they'll be good for me
Yeah, if it's good for you then it's good for me
If it?s good for you then it's good for me
So, come on kids eat those pills
You've got your whole life to lose
And we've got so many friends
That wear their feet too big for their shoes
We've got cities to visit
We've got trees we've yet to live in
So get yourself on top of me
Before I'm gone, gone, gone
And we've got so many friends
That wear their feet too big for their shoes
We've got so many friends
That wear their feet too big for their shoes
We've got so many friends
That wear their feet too big for their shoes
We've got so many friends
That wear their feet too big for their shoes
