During their set at Riot Fest Toronto earlier this evening, Canadian-natives Alexisonfire announced that they have officially reunited. “Thank you for believing in this band when we couldn’t even believe in this band,” guitarist Wade MacNeil said to an immaculate crowd. “Thank you for sticking with us. We promise to never leave you again. No more sentimental shit. Alexisonfire is officially back.”

The band initially announced their breakup in August of 2011, which they followed by performing a run of “official” farewell shows in 2012. Since then they have released two exclusive vinyl boxsets, the first of which (limited to 1,000 copies) sold out in about 30 minutes.

Earlier this year, AOF revealed that they would be reuniting for a handful of worldwide festival performances, but it was uncertain if the band had a definite future.
