The announcement

"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," band co-founder Brad 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," he added.

“My relationship with Brian was complex. 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," he continued.

The 1990s boy band was the source of several well-known songs, including "Summer Girls" (1999), "Girl on TV" (1999) and "Simon from Sydney."

"The group’s pop-rap single 'Summer Girls' became their biggest hit and was often referred to as “The Abercrombie & Fitch” song because of the popularity of the lyric 'I like girls that wear Abercrombie & Fitch.' The song helped to catapult their 1999 album 'LFO' — which also included hit single 'Girl on TV' — to No. 21 on the Billboard 200," according to Variety.

The group launched in 1995, seeing success in the late 1990s before their 1999 hit song and album. The group played until 2002, taking a short break and reunited without Gillis until 2010 when Cronin died of a stroke.

The cause of death for Gillis has not yet been revealed, with his loss coming at a young age alongside other band members of LFO who are gone far too soon.
