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.
Don't bend
Don't blink
Don't beg
Don't scream
Don't whine
Don't fight
Don't tell me, don't tell me, don't tell me
Don't feel
Don't tear
Don't kiss
Don't care
Don't touch
Don't want me, don't want me, don't want me
Something's so sick about this
My misery is so additive
I'm halfway there with your Northshore from the floor
singing to you over my shoulder
Don't run
Don't hide
Don't hurt
Don't lie
Don't breathe
Don't try
Don't find me, don't find me, don't find me
Don't cringe
Don't clench
Don't look
Don't flinch
Don't know
Don't go
Don't leave me, don't leave me, don't leave me
Something's so sick about this
My misery is so additive
I'm halfway there with your Northshore from the floor
singing to you over my shoulder
Don't sing
Don't talk
Don't yell
Don't laugh
Don't think
Don't speak
Don't save me, don't save me, don't save me
Don't stay
Don't plan
Don't heal
Don't mend
Don't take
Don't send
Don't love me, don't love me, don't love me
Something's so sick about this
My misery is so additive
I'm halfway there with your Northshore from the floor
singing to you over my shoulder [x4]
