Horizon Theory

Based on verified information in my knowledge base:

Horizon Theory is a hard-hitting rock/metal band that emerged from Ontario, Canada. Formed around 2010 by vocalist Mike LeBlanc and drummer Mike Falcone, the band quickly built a reputation locally and beyond for their intense blend of heavy riffs, melodic hooks, and powerful vocals. They established a strong DIY ethic, self-releasing their music and building a dedicated fanbase through relentless touring across Canada and sharing stages with notable acts.

Their sound, often described as a mix of hard rock and metalcore, is showcased on releases like their 2015 full-length album "The Writing On The Walls" and the earlier "The Reckoning" EP. Tracks like "Propaganda," "White Knuckle Sucker Punch," "Radio Silence!," and their cover of Flobots' "Handlebars" became fan favorites, known for their aggressive energy and catchy choruses. Horizon Theory carved out their space in the Canadian heavy music scene through consistent output and a powerful live show.
