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.
Well, then the man with two brains says:
Been thinkin' bout the conversations, our situation
My frustration, leading to your suffocation
Feel uptight and my thoughts deranged and insane
Like The Man With Two Brains
So, I forgot the neurotic, got into the psychotic
All those words haven't heard, you're kind of erotic
Got no guilt, got no mind, got no reason, got no time
I'm high on the sly
(It will be OK)
I don't know about that
(It's the American way)
Yeah, maybe that's where it's at
(You were raised that way)
The Europeans say
(The Man With Two Brains)
Well then The Man With Two Brains says "It's a science
I've got one for my actions, one for my conscience
Yeah, one's for the sex and the other's for the consequence"
Then The Girl With One Brain says "You make no sense,
You make no sense"
Then, the anti-cruise takes form in the frame of a young woman
From a passionate scene to a sterile queen
I put a bottle of Ed's Red in my head, a little dead
And surprised when you said:
(It will be OK)
I don't know about that
(It's the American way)
Yeah, maybe that's where it's at
(You were raised that way)
The Europeans say
(The Man With Two Brains)
Well then The Man With Two Brains says "It's a science
I've got one for my actions, one for my conscience
Yeah, one's for the sex and the other's for the consequence"
Then The Girl With One Brain says "You make no sense,
You make no sense"
(it's cool, cool)
Well The Girl With One Brain says "It's not a science,
You can't have one for your actions and one for the consequence
It's all about sex, so what's the difference"
Then, The Man With Two Brains says "You make no sense"
(you make no sense, no sense, you make no sense, no sense)
The Europeans say: (It will be OK)
Kick back and rela (The Man With Two Brains)
Roll on the flow track (It will be OK)
The Europeans say (The Man With Two Brains is all about sex)
