Blu has connected with veteran producer Fat Jack for a project titled Underground Makes The World Go Round. The collaboration has been released through Freestyle Fellowship member Self Jupiter’s The Order Label.

The seven-track set features Blu trading raps with Myka 9, Abstract Rude, Busdriver, Medusa and Cashus King.

“Blu shows his love for his city and his hometown heroes Freestyle Fellowship on this album,” Self Jupiter recently told HipHopDX. “He gives them their flowers now and history lessons on how he as an MC first heard of Aceyalone, Myka 9, Peace and me — better known as known as the Freestyle Fellowship. DJ Fat Jack delivers the perfect backdrop for this congratulatory ode.”
