Matthew Tyler Musto (born 1990), known professionally as blackbear, is an American hip hop recording artist, singer, songwriter and record producer. His most notable songwriting credit is on Justin Bieber's "Boyfriend," but he's also worked with Mike Posner, G-Eazy and Hoodie Allen. He used to be your run of the mill singer-songwriter until that massive co-wrote and then he went towards R&B / hip-hop. His downtrodden and drugged out music has amassed millions of plays on Soundcloud and Spotify, despite not having a solo hit or any type of radio backing. He released two EPs in 2016 and an LP late 2015 Drink Bleach Cashmere Noose I'm really surprised there isn't any type of major label support for him since he's proven he has the following and music to build something huge.
