Ty Dolla $ign is focused on two things. One, making music, two, getting his younger brother TC -- who is currently serving a life sentence for murder, out of prison.

We've been hearing about his bro through Ty's music. Ty Dolla even named his debut album Free TC. This week, the Los Angeles singer-songwriter released a documentary by the same name about his brother's incarceration.

In the Daniel Kaufman-directed 12-minute film, Ty' and his family members -- mom, sister and TC's wife -- discuss TC's childhood, and the situations surrounding his case.
