In a letter posted on the Riot Fest website, festival organizers write that this year's Denver festival is "simply not possible." The news follows the death of Riot Fest organizer Sean McKeough last December.
Riot Fest previously took place annually in three cities: Denver, Chicago and Toronto. The Toronto event did not take place last year. Chicago's event is still on for 2017.
Relive highlights from Riot Fest with our snapshots from last year's Riot Fest Denver featuring Misfits and Sleater-Kinney and from the 2015 event featuring Modest Mouse and Iggy Pop.
