This week we spoke with Robert Trujillo, who you might know as the bassist of Metallica and has been producing a music documentary called JACO about legendary bassist Jaco Pastorius.

We discuss how Robert first became interested in profiling such an iconic player and what it was like producing this film which includes interviews with Herbie Hancock, Flea, Wayne Shorter, Jerry Jemmott, Joni Mitchell, Bootsy Collins and Sting.
