"I knew Rock House's had a good repuation for working with artist, when I got my chance I jumped on the opportunity. It was an amazing expeirence working with the team, they are total pros! My program is for anyone who wants to kick that low end in a heavy way. I cover more modern techniques being used in today's metal. I think people will have a lot of fun with my program."
