The Ohio heavy metal event FireFest 2014 was cut short this weekend after gunfire reportedly erupted outside the venue in a Cleveland suburb. 

Saturday night's lineup was supposed to feature headlining performances from Ringworm and Death Before Dishonor.  But instead, 19 Action News says a large fight escalated out of control. 

Police say the brawl involved guns, machetes, and knives.  Five victims had to be taken to local hospitals, and more than 20 people were taken into custody. 

Charges are expected to be filed on Monday.
