Grindmother is a Canadian grindcore musical project centered around a mother, known only by her stage persona "Grindmother," and her son, guitarist and producer Rayny Forster. Based in Windsor, Ontario, the band formed in 2015 and achieved widespread viral fame for the stark contrast between the intense, aggressive nature of the music and the lead singer’s age. Before fronting the project, Grindmother worked as a social worker and enjoyed hobbies like organic gardening and meditation.

Band History and Success

Retirement and Final Shows

Following a multi-year hiatus, the band announced in July 2025 that Grindmother had been diagnosed with advanced dementia. To mark retirement from the stage, they organized a brief, emotional farewell tour consisting of two final sold-out concerts in Montreal and Toronto in December 2025.

Because of her declining health, guest vocalists (including Alissa White-Gluz, formerly of Arch Enemy) handled the majority of the singing duties, while Grindmother took the stage to perform the very last song of each night. In February 2026, she moved into a long-term care facility. Although her live performances have permanently concluded, Forster has stated that previously unreleased music and a variety of other projects being prepared for future release.
