I definitely understand where you're coming from, but there's also a flip side to it that people like me would really enjoy.
If there's going to be hours upon hours of black/death metal no matter what (which I imagine is the case at Deathfest), I'll be extremely appreciative of any bands who bring a bit of diversity to the day and contrast the blastbeats with some different material.
Likewise, if I know I'm seeing a bunch of prog/power all day, the band that brings out some ripping black metal for a few songs is going to be a really nice change of pace for a little while.
