Tonight's Summer Slaughter concert at the the Ritz Theatre in Ybor City, Florida was delayed by nearly two hours after someone was reportedly overheard threatening to shoot the singer of JOB FOR A COWBOY, one of almost a dozen acts taking part in the traveling festival.According to TBO.com, management at venue became worried and called police at around 5:34 p.m. Nearly 1,000 people were evacuated from 6 to 7:30 p.m. and part of 7th Avenue was closed. No weapons were found in the club and the people who had been evacuated were patted down before they were allowed back in. JOB FOR A COWBOY drummer Jon "Charn" Rice told BLABBERMOUTH.NET, "Just to clarify the events that happened this evening, a note was passed to the bartender stating that during our set a man with two knives and a gun was going to hurt people. Cops were called and after the proper precautions were taken, the show set off again, albeit a bit behind. No one was hurt and everyone involved is safe." Stephen Rafferty of The Metal Observer, who was in attendance at tonight's concert, told BLABBERMOUTH.NET, "JOB FOR A COWBOY finished their set but we're almost two hours behind." He added, "VEIL OF MAYA just did 25 minutes. Lots of people came late and had no idea what was going on. Crowd and police were tremendous."
