“Sister” is the third single off K.Flay’s latest album, Solutions. The track explores sisterly bonds in life and the importance of having someone to support you. The rhythm of the song is cheerful, and the synthesizers make it a perfect track to dance to.
The music video is also entertaining and the singer had to make an extra effort for it. She had to learn the lyrics of the song backward, because all of the action had to happen in reverse.
