This song is by Wolf Alice. They are a four-piece alternative rock band from North London, formed initially as a two-person band in 2010. Its members since 2012 are Ellie Rowsell (vocals, guitar), Joff Oddie (guitars, vocals), Theo Ellis (bass), and Joel Amey (drums, vocals).
This was the first song that I heard of this band and fell in love with this song and the video. The video made me miss all my friends and sisters. I have many sisters as cousins but not as a sibling. I have a younger brother but I always miss having a sister. I wish I had one sister too.
I Like the voice of Ellie and their compositions. These people are creative. They make good music.
