The global punk rock and alternative music communities are mourning the loss of Chad Gilbert, the foundational lead guitarist, primary songwriter, and co-founder of the influential Florida pop-punk band New Found Glory. Gilbert passed away peacefully in his sleep on the morning of September 20, at the age of 45, following a prolonged and courageous battle with cancer. His death was officially announced by his bandmates and his wife, Lisa Cimorelli, through coordinated statements on social media, drawing an outpouring of grief and tribute from across the music industry.
Gilbert’s passing comes roughly six months after he publicly disclosed that he was battling brain cancer, a devastating development in a multi-year health ordeal that began when he was first diagnosed with liver cancer in 2021. Despite aggressive medical interventions, including advanced immunotherapy treatments designed to combat tumors pressing against his brain, Gilbert ultimately succumbed to the illness. According to his family and bandmates, he spent his final moments surrounded by those he loved most, passing away with his wife and mother by his side at a hospital that quickly filled with visiting friends and peers in a testament to his deeply cherished status within the music community.
A Life Defined by Pop-Punk Innovation
Born in 1981, Chad Gilbert’s musical destiny took shape in Coral Springs, Florida, in 1997. Alongside vocalist Jordan Pundik, bassist Ian Grushka, and original guitarist Stephen Klein, a 17-year-old Gilbert helped form New Found Glory, a band that would go on to fundamentally redefine the sound and aesthetic of turn-of-the-millennium pop-punk. While many bands of the era chased fleeting commercial trends, New Found Glory anchored their sound in high-energy guitar riffs, infectious melodic hooks, and hardcore-infused rhythm sections, creating a distinctive blueprint that influenced an entire generation of alternative musicians.
As the band’s principal lyricist and lead guitarist, Gilbert was the creative engine behind New Found Glory’s most enduring anthems. Tracks like "My Friends Over You" and "Head on Collision" transcended the underground scene to become definitive pop-punk staples of the early 2000s, receiving heavy rotation on MTV and alternative radio stations worldwide. Over nearly three decades, Gilbert’s distinct musical sensibility helped steer the group through more than a dozen studio albums, relentless global touring schedules, and a consistent evolution that earned them both critical praise and fierce commercial loyalty.
Beyond his work with New Found Glory, Gilbert maintained an active footprint in the broader punk rock ecosystem. He lent his distinctive guest vocals to Fall Out Boy’s breakout 2005 album, From Under the Cork Tree, and contributed complex guitar work to tracks on their subsequent 2007 release, Infinity on High. His production work and behind-the-scenes mentorship of emerging alternative acts further cemented his reputation as a pillar of the modern punk scene.
A Multiphase Battle with Cancer
Gilbert’s health journey was characterized by resilience, transparency, and a refusal to let terminal diagnoses define his creative output. In 2021, he was diagnosed with liver cancer, a shocking development that forced him and the band to navigate unexpected health hurdles while maintaining their professional commitments. Even as he underwent intense treatments, Gilbert continued to engage with his fans, offering updates that balanced the stark realities of oncology with an unwavering, upbeat philosophy.
In early 2024, however, the medical battle intensified when doctors discovered three tumors pressing against his brain. The neurological impact of the condition led to a loss of sensation on the left side of his body, effectively sidelining his ability to play guitar live and preventing him from performing alongside his bandmates during their scheduled appearances, including a poignant nod from the stage by New Found Glory at the 2026 Vans Warped Tour revival in Washington, D.C.
Despite the physical toll, Gilbert maintained a remarkably positive outlook. In an extensive interview with Rolling Stone in April, he articulated his perspective on mortality and recovery with characteristic humility and strength. "It felt good to know that there’s still a battle to be going on and that I can recover from this and grow stronger from this," he stated at the time. While acknowledging the inevitable moments of emotional exhaustion and grief, Gilbert consistently redirected his focus toward community, connection, and the restorative power of music.
Tributes and Industry-Wide Remorse
The announcement of Gilbert’s passing triggered an immediate wave of tributes from prominent musicians, lifelong friends, and legions of devoted fans. Blink-182 vocalist and bassist Mark Hoppus, who famously navigated his own public battle with diffuse large B-cell lymphoma following a 2021 diagnosis, took to social media to honor his late peer.
"Chad was the best friend to every person he met. The most positive and creative force in any room he walked into," Hoppus wrote. Reflecting on Gilbert’s temperament throughout his illness, Hoppus added, "These past years he fought his sickness with the soul of a joyous, courageous warrior. You’ll be sorely missed by more people than you could ever imagine. See you on the other side."
New Found Glory released a joint statement that underscored not only his immense musical legacy, but also his profound dedication to his personal life. "We are devastated and shocked by how quickly he left us, yet so grateful for how peacefully and smoothly he went," the band shared. "He was a legendary musician, but his favorite accomplishment was being a husband and father. His biggest dreams came true."
Reflecting on his nearly three decades within the group, his bandmates emphasized that Gilbert’s artistic standards permanently elevated those around him. "Chad’s guitar playing, songwriting, humor, and relentless drive helped shape New Found Glory for nearly three decades," the band stated. "While we are devastated to lose him, we are so grateful for the incredible life he lived, the memories we shared, and the brotherhood we had. His influence will always be part of New Found Glory and his spirit will be felt on every stage we stand on, with every note we play."
Legacy and Cultural Impact
Gilbert’s personal life was frequently intertwined with the high-profile alternative music scene. He shared a widely publicized, multi-year relationship with Paramore frontwoman Hayley Williams, whom he married in February 2016 before separating in late 2017. Later in life, he found profound fulfillment in his marriage to Lisa Cimorelli, with whom he built a family, frequently expressing that fatherhood and partnership were his most cherished achievements.
The broader cultural implications of Gilbert’s death mark the end of an era for the second-wave pop-punk movement. As bands from the late 1990s and early 2000s face the inevitable realities of aging and health crises, the loss of foundational architects like Gilbert highlights the fragile human core behind the genre’s high-octane youth culture.
Yet, the institutional framework that Gilbert helped build remains robust. Through decades of relentless touring, influential songwriting, and a collaborative spirit that bridged underground hardcore ethos with mainstream accessibility, Chad Gilbert leaves behind a recorded legacy that will continue to resonate through future generations of alternative musicians. His contributions ensure that while the physical stages may miss his presence, the foundational notes of modern pop-punk will forever carry his unmistakable signature.
