5 years ago 17-year-old Cassia O’Reilly started making music under the pseudonym Bonzai. During this time she’s enjoyed an impressive array of critical acclaim, worked with with Mura Masa and has since gone through a transformation, both as an artist and as a human being. Now the Irish artist is reborn as Cosha and released the R.I.P. Bonzai mixtape on Columbia Records last June. Lead single Do You Wanna Dance is produced by Rostam, known for his work with the likes of Frank Ocean, Solange and Haim.
