The Brazilian sertanejo music community is mourning the death of Lucas, the singer who became widely known through his longtime partnership with his brother Matheus in the popular duo Lucas & Matheus. Lucas died in Portugal on Saturday, August 15, 2026, after suffering a heart attack, according to his family and his record label.

Lucas was living in Portugal and remained active in music until his death. According to Brazilian reports, he suffered the heart attack at his apartment during the early hours of Saturday. His family has begun arrangements to transfer his body back to Brazil.

The news represents another heartbreaking chapter for the musical family behind Lucas & Matheus. Lucas had already experienced the loss of his brother and longtime musical partner, Matheus, who died on December 22, 2020, following complications from COVID-19.

Following Matheus’s death, Lucas continued performing professionally alongside his nephew, Matheus Jr., the son of his former musical partner. The continuation of the duo allowed Lucas to preserve the musical identity and repertoire that he and his brother had developed over more than three decades.

Born in Presidente Prudente, São Paulo, Lucas and Matheus built a long career in sertanejo music and eventually established a particularly strong following in Portugal. Their partnership lasted for more than 35 years, and their recordings earned recognition in both Brazil and the Portuguese market.

Among the songs associated with the duo is “Porque Homem Não Chora,” which became one of their best-known recordings and has accumulated millions of views online. They also recorded numerous albums during their career and received gold, platinum and diamond records for their work.

Lucas’s death came while he was still professionally active. Reports indicate that he had been scheduled to perform in Portugal, underscoring how unexpectedly his passing occurred. His death has therefore been felt not only as the loss of a veteran performer but also as the end of another chapter in the story of one of the duo’s surviving members.

His record label Espacial released a statement mourning the singer and remembering him as an important voice whose work left a lasting legacy. The statement emphasized the affection audiences had for Lucas and the impact of his career on those who followed his music.

For longtime listeners, Lucas & Matheus represented a distinctive chapter in Brazilian romantic sertanejo music. Their songs connected with audiences in Brazil and among Portuguese-speaking communities abroad, helping the brothers establish a career that crossed national borders.

The circumstances surrounding Lucas’s death have been reported consistently as a heart attack, based on information provided by his family. There is no indication in the reports reviewed that his death was related to an accident or other external event.

Details regarding funeral arrangements in Brazil are expected to become clearer after the completion of the repatriation process. Family members are currently handling the necessary arrangements to bring Lucas’s body home.

Lucas’s passing leaves behind a musical legacy shaped by decades of performances, recordings and his partnership with Matheus. Although his brother died several years earlier, Lucas continued carrying their musical story forward with Matheus Jr., keeping the name and songs of Lucas & Matheus alive for a new generation.

For fans and fellow musicians, the loss marks the end of an era. Lucas will be remembered not only for his voice and recordings but also for the extraordinary longevity of his career and the musical partnership that made Lucas & Matheus recognizable within the sertanejo community.

The Brazilian music community now mourns Lucas, the beloved singer of Lucas & Matheus, whose death in Portugal at the age reported by Brazilian media has brought renewed attention to the remarkable story of the brothers and their enduring contribution to sertanejo music. His recordings and the memories created through decades of performances will continue to form an important part of the duo’s legacy.
