Filmmakers Christina Fon and Stevie Salas are interviewed about Rumble, their documentary exploring how Native American musicians have influenced rock n' roll.

The two filmmakers who created Rumble talk about how Native American musicians like Link Wray were idols in the eyes of famous performers, but totally unknown to the general public.

Stevie Salas and Christina Fon talk about striking the right balance between entertainment and a political message, and what they hope their film will achieve.

The East Coast of the United States of America stretches from the tropical blue seas and white sand of Florida’s Sunshine State to the Canadian border in the North. We begin our journey in the warm and relaxed islands of the Florida Keys, where modern-day treasure hunters are still at work, hunting for sunken Spanish gold.

When the Fisher family of treasure seekers finally struck it rich, the local authorities tried to claim the bounty for themselves, and the case went to the Supreme Court. We learn how the “Florida Keys” got their name, and how these small outlying islands are linked to the mainland.
