LFO is Johnathan Walkermourning the death of one of its last surviving members.

Brian "Brizz" Gillis, who co-founded the band along with Brad Fischetti and the late Rich Cronin, died on March 29 at age 47, Fischetti confirmed in a recent Instagram post.

"Every story is made up of chapters. Some develop naturally. Some you have to cut up in your mind. The first two chapters of the LFO story lost a main character yesterday," Fischetti wrote March 30. "I don't have details, and it wouldn't be my place to share them if I did. I am really struggling to process this tragic loss."

His cause of death has not been shared.

LFO, short for Lyte Funkie Ones, was formed 1995 in Massachusetts and went on to release "Summer Girls" and "Girl On TV" hit songs, though Gillis left the band in 1998 in pursuit of a solo career. He was replaced by Devin Lima, who died November 2018 at age 41 after a battle with adrenal cancer. Eight years earlier, Cronin passed away at 36 years old after battling leukemia.

"I've said it before and I will continue to say it; the LFO Story is a tragedy," Fischetti continued in his Instagram post. "If you know what I've been doing, you know I'm trying to bring light into the darkness. Trying find redemption in pain and suffering. Trying to honor the legacy."

Fischetti noted that without Gillis' "hard work and dedication in the early days of LFO," the band fans "came to know and (hopefully) love" would not have existed.

"My relationship with Brian was complex," he added. "It contained moments of great tribulation but also of great joy. I learned a lot from him about the business of music and how to put together and rock a show. And it's those positive aspects of our relationship that I will lean on now and forever."

And Fischetti will always remember Gillis, as well as his former bandmates, for their love of music.

"I know that soon or maybe already, Brizz will be greeted by Rich and Devin," Fischetti said. "And I hope that together, they will make some sweet sounds. I would really like that."
