Martian Awareness Ball Tickets

Martian Awareness Ball is not a single act, but a fluid, ongoing collaboration that brings Toronto’s vibrant indie scene to life. Founded in 1978 by Mary Margaret O’Hara and her brother Marcus O’Hara, the concept began as a Martian-themed Saint Patrick’s Day party and evolved into a celebrated annual gathering. The event has grown into a hallmark on Toronto’s music calendar, staged at the celebrated Horseshoe Tavern in downtown Toronto each March. The 47th edition took place around March 17, 2025, and the 48th edition was scheduled for March 14, 2026, continuing the tradition of rotating guest performers and spontaneous musical moments. The Ball is known for its unpredictable, free-for-all party atmosphere, with a different lineup of guest artists each year, reflecting the city’s diverse indie community.
