South Central Los Angeles-based artist Wil$on has loved ones behind bars. And he's singing for them on ultra-smooth Cooks&Jango-produced track 'Letter.' It's definitely put the 22-year-old artist on our radar.

"So we all know mass incarceration is a big problem in the United States, 'Letter' is about having loved ones in the prison system. The song is basically how my friend Lonnie Williams and cousin Darion Thompson got there and the questions they ask about what’s going on in the outside world," he says.
