Irish musician Glen Hansard, best known as the co-writer of the Oscar-winning song “Falling Slowly,” died Wednesday, prompting an outpouring of tributes from across the entertainment industry. Hansard, who fronted the bands The Frames and The Swell Season, was remembered by Bruce Springsteen, Bono, Wilco’s Nels Cline, Finneas, Cat Power, Rachel Zegler, Lin-Manuel Miranda, and Warren Ellis. Springsteen described Hansard as an “angelic presence,” while Bono called him the “voice of the streets” and recalled their shared participation in the Christmas Eve Busk, the annual charity event Hansard organized in Dublin. Bono, the U2 frontman, noted that Hansard often joined him for the busk, a Dublin tradition that raises funds for homelessness services. “Falling Slowly,” which Hansard co-wrote with Markéta Irglová for the 2007 film “Once,” won the Academy Award for Best Original Song. The film itself, a low-budget indie musical, became a cult hit and earned Hansard and Irglová widespread acclaim. His sudden death early Wednesday morning has prompted an immediate wave of grief from fans and fellow musicians alike, with many citing his raw emotional performances and his deep connection to Dublin’s streets and music scene. Hansard’s impact extended beyond his own work; he frequently collaborated with other artists and was a fixture at the Christmas Eve Busk, which he helped turn into a major annual event. Further details about the circumstances of his death have not been released.
