The music world tragically lost another member of a popular 90s music group, notably marking the third member of the group to pass away. 

According to Fox News, Brian "Brizz" Gillis of LFO, the band most known for its hit song, "Summer Girls," has died at the age of 47. As of this writing, the cause of death has not been made public.

Gillis was one of the band's founding members and the third founding member to die.

He founded the band with Rich Cronin in 1995.

Background

The band was first signed by Lou Pearlman's record label Trans Continental Records, a label known for signing massive "boy bands" like NSYNC and Backstreet Boys.

LFO is best known for its hit single "Summer Girls," which topped the charts in 1999. The song features a catchy melody, with lyrics that reference various pop culture icons and events from the '80s and '90s.

"Summer Girls" was also widely known as "the Abercrombie & Fitch song," Fox News noted.

In addition to "Summer Girls," LFO had other popular songs, such as "Girl on TV" and "Every Other Time."

The group's music style blended pop and hip-hop influences, with catchy hooks and fun lyrics. LFO's popularity was short-lived, and the group disbanded in 2002. Rich Cronin passed away in 2010, but Brad Fischetti continues to perform LFO's music as a solo artist.

Despite their relatively brief time in the spotlight, LFO left a lasting impact on pop music in the late '90s.

Tributes pour in

Given the band's popularity at the time, a number of fans shared their thoughts on the tragic news.
