The Big Ol’ Nasty Getdown is a Los Angeles‑based musical collective led by bassist/producer John Heintz. It's not just a band—it’s a revolving-door funk, soul, rock, R&B jam project that brings together legendary musicians (members of Earth, Wind & Fire, Parliament‑Funkadelic, Red Hot Chili Peppers, Primus, Living Colour, and more) with fresh talent in week‑long immersive recording retreats. The result is a vibrant, genre‑blurring sonic tapestry—heavy on groove, improvisation, and collaborative energy, with every track feeling like a spontaneous jam session.
