(KTLA) – The music world is mourning the loss of Sam Rivers, a key figure and bassist for Limp Bizkit, who passed away at 48, as announced by the band on Saturday.

Limp Bizkit broke the news on Instagram, choosing not to disclose the cause of Rivers’ untimely death.

“Today, we bid farewell to our brother, our bandmate, our heartbeat,” the band shared. “Sam Rivers was more than just our bassist — he was pure magic. He provided the pulse that drove every song, the calm within the chaos, and the soul of our sound.”

The tribute continued, highlighting Rivers’ unique contributions: “From the moment we first played together, Sam infused a light and rhythm that were irreplaceable. His talent flowed effortlessly, his presence left a mark, and his heart was immense. We’ve shared countless moments — wild, serene, and beautiful — all enriched by Sam’s presence.”

The band concluded with heartfelt words, “He was truly one-of-a-kind, a legend among legends. His spirit will resonate in every groove, on every stage, and through every memory we hold dear.”

The message was signed by Rivers’ bandmates, Fred Durst, Wes Borland, John Otto and DJ Lethal.

The nu-metal band was formed in 1994 in Jacksonville, Florida. Rivers met lead vocalist Durst while the two were working at a Chick-fil-A restaurant, according to Deadline. 

Limp Bizkit grew in popularity and became one of the genre’s most influential groups of the late ‘90s to 2000s. Best known for tracks such as “Break Stuff,” “Rollin’ (Air Raid Vehicle),” “Take A Look Around,” and “My Way,” the band has released six studio albums, many of which have been platinum-certified. 

In 2015, Rivers left the group due to liver disease complications from excessive drinking, Deadline reports. He received a liver transplant and, three years later, rejoined the band and played with them until his death.

“We love you, Sam,” the band’s Instagram message reads. “We’ll carry you with us, always. Rest easy, brother. Your music never ends.”
