Raised on the Rosebud Indian Reservation in South Dakota, Frank Waln discovered hip-hop when he saw something glistening in the sun on the side of a gravel road. It was a scratched-up copy of Eminem's The Marshall Mathers LP. He took it home, and he says the record "blew his mind." Since then, Frank has used his music to raise awareness of Native American issues. He performs alongside other activist musicians like Willie Nelson and Neil Young.
