After posting an absurd amount on Twiiter about their forthcoming mixtape, the Star Trak duo behind Chester French have finally released Jacques Jams Vol 1: Endurance. And you know what? It's really, really good! It features appearances by everyone from Janelle Monae and Solange Knowles to Diddy and Talib Kweli. Even better, it's a compltetly free which means the money you would have dished out on this 25 track joint can be used to purchase the group's debut album, Love The Future, when it drops on April 21st.
