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.
Dignified in what she does when she sings
The smile that she brings to all of you unaware
Of what's to come I said tell me what's to come
Green is the color of my envy
It's the color of fame
So I'm gonna write it down
Gonna scream it out
And I'm never gonna be the same, again, again
Fear is the color you've all exposed
Now I gotta get up here
And prove the importance
Of my clothes of my pose I suppose, again, again
Hard core superstar by far
You're the ultimate star
Hard core superstar by far
Do you wanna be a...
Hard core superstar by far
You're the ultimate star
Well, that's what you are
You're gonna be a star
Do you wanna be a superstar?
Clever in what she does competing for the attention
Of those people that you know
My whole life revolves around
Your absence until I can't remember
What I was or what I am
Who I know or what I know or where I go
Every moment was that moment
Every day was that day
Every second was that second
And I've lost myself again
Yes, I've lost myself again
Hard core superstar by far
You're the ultimate star
Hard core superstar by far
Do you wanna be...
Do you wanna be a superstar?
Well, that's what you are
You're gonna be a star
Do you wanna be a superstar?
Soon my face will be on every magazine
Then my voice will be on every frequency
Take my heart, while you're at it
Why don't you sign me up to sell me out
Why don't you sign me up to sell me out
Why don't you sign me up to sell
Hard core superstar by far
You're the ultimate star
Hard core superstar by far
You're the ultimate star
Do you wanna be a superstar?
Do you wanna be a superstar?
I am my angel 'til death I do, I saw my first angel
It was you
I am my angel 'til death I do, I saw my first angel
It was you
I am my angel 'til death I do, I saw my first angel
It was you
