Speaking to CNN Darrell Roberts, who had been travelling with his son, said detectives woke him up on Saturday to tell him Matt had passed away. "I was wakened at 8:50 this morning by some detectives beating on my door,” Roberts said.
“It’s always scary as a parent, they were in suits and that's when they told me. They asked me if Matt Roberts was your son, I said yes, and they said 'we have bad news to tell you, Matt deceased last night.'”
According to CNN West Bend police received a call on Saturday saying that a man was "either asleep or passed out in the hallway of his hotel,” he was later declared dead. The cause of death has not yet been determined and an autopsy is scheduled.
Mr Roberts said his son had struggled with anxiety and an addiction to prescription drugs. "I know he had prescription drug addiction,” he said. “He suffered greatly from anxiety.
"It's crazy as a performer; he never liked crowds or liked places he didn't know about as a baby, as a child, and this was his way of dealing with it and me and him talked about it often.” However Mr Roberts had thought his son had beaten his addiction.
He now plans to attend the event his son was scheduled to perform and inform the crowd about his death. "That's what he would have liked, he put all this energy and effort to come out here to perform,” he said. “I’ll put his guitar on stage and light it up and I'm going to say thanks to everybody and leave and go home in the morning.”
