Read this: A tribute to Power Trip’s Riley Gale: The people’s champion of metal
Matt continued: "I know that those guys can still pull it together and I hope they can still pull it together and do what they do. Riley will be greatly missed. Everyone remembers him as being an undeniably incredible frontman which he was with a voice that sounded like no-one else.
"I think Power Trip was doing something very different that other people weren't doing and it was amazing they were able to bring so many fans of so many different genres into one band. So we want to pay tribute here and play a little song, we hope we do it a little bit of justice."
