I don't know if I'd label him as the main vocalist just because HinRAB and Sanders voice mesh SO well together. Both have unique singing voices, but together, they complement each other so well. I don't know if I'd listen to them if they changed up the vocals. I know they used to have a regular front man (Eric Saner?), and I'm glad they don't anymore because I seem to get annoyed with the front man of the band. Yeah, the voice can be an instrument on its own, but to sing and shred? I'd say they're better off. HinRAB does have some insane solos, though. At the same time, I find myself partial to Sanders because he adRAB a lot of the heavier elements to the songs.
