Sam Rivers — the bassist for the rock-rap group Limp Bizkit — has died … in keeping with an official assertion posted to the band’s Instagram.

The group introduced Sam’s passing Saturday night … revealing he handed away earlier within the day and calling him their “heartbeat.”

Sam wasn’t only a bass participant, the group say — he “was pure magic. The heart beat beneath each track, the calm within the chaos, the soul within the sound.”

Exterior of the music, the band writes that Sam was a once-in-a-lifetime particular person and a legend amongst legends.

The message ends, “Relaxation straightforward, brother. Your music by no means ends.”

Rivers was 48.

RIP

Story growing …
