Alongside guys like McCoy and Knudson (both of whom have toured with Russian Circles), RC guitarist Mike Sullivan is also redefining what being a guitar player in a heavy band means by figuring out a way to implement chugging hardcore riffs into an atmospheric arena and making both dynamics more powerful in the process. Sullivan can also two-handed tap and live loop like a champ, making him a triple threat onstage. To be honest we have no idea how he'll be able to pull off some of the sonic textures on the band's latest album Memorial—but we have no doubt he'll find a way to do it in stunning fashion.
