Alessia Cara performs an acoustic version of her song “Four Pink Walls” for Vevo dscvr.

“Four Pink Walls,” the song on her debut album “Know-It-All” that she has sole writing credit on, first appeared on her EP with the same name.

On her Tumblr, Alessia explained her intention behind the song.

this song was definitely a challenging one for me. it was the first song I wrote completely alone & not in a studio. with this song, i really wanted to tell my story. Although it might be less relatable to other people because of its specific details to my life, i just needed to express what had been going on in my brain.
