The regional Mexican music world was shaken on Tuesday, January 7, when Banda MS confirmed the death of one of its musicians, pianist Gerson Leos. The group announced the loss through its official social media accounts, plunging fans and fellow artists into mourning and sparking an outpouring of messages of support.
In a post shared with more than four million followers on Instagram, the band published a photograph of Leos accompanied by an emotional farewell. The message honored both his musical contributions and his personal impact on those around him.
"Today we say goodbye to Gerson with deep sadness, but also with gratitude for everything he left behind in the lives of those who knew him," the statement read. "Our hearts are with his family, friends, and loved ones during this very difficult time. Gerson will always remain with us, in his music, in our memories, and in every person he crossed paths with."
The announcement immediately prompted questions from fans about what had happened and how the musician died, especially given the sudden nature of the news.
According to local media reports in Sinaloa, Gerson Leos died after suffering a sudden heart attack in the first days of January 2026. The reports indicate that the pianist collapsed while playing a baseball game in Mazatlán, Sinaloa, where the band is based. Despite efforts to assist him, the cardiac event was fatal.
Leos' death was officially confirmed by Banda MS on Tuesday afternoon, ending hours of speculation across social media. No prior health issues had been publicly reported, adding to the shock felt by fans of the genre and the group.
Banda MS is one of the most influential and commercially successful acts in Mexican regional music, known for chart-topping hits such as Mi mayor anhelo, El color de tus ojos, and No me pidas perdón. While Leos was not one of the founding members, he was a key part of the band's musical backbone, contributing as a pianist and multi-instrumentalist. In addition to piano, he was known for his versatility on guitar and bass, qualities that made him a valued collaborator within the group.
Local outlets in Mazatlán highlighted that Leos was also active outside of music, frequently participating in recreational sports such as baseball. His death during a game underscored the unexpected and devastating nature of the incident.
Since the announcement, fans have flooded the band's accounts and Leos' personal social media with tributes, photos, and condolences, many praising his talent and expressing disbelief at his passing. Fellow musicians from the regional Mexican scene have also shared messages honoring his career and sending strength to his family.
At this time, Banda MS has not released further details regarding funeral arrangements or tributes, but the group's message made clear that Leos' legacy will endure through the music he helped create.
As the regional Mexican community continues to grieve, the sudden loss of Gerson Leos serves as a sobering reminder of how fragile life can be, even for artists in the midst of active careers. His contributions to Banda MS remain part of the sound that has defined a generation of fans, and his memory now lives on through the songs that continue to resonate across Mexico and beyond.
