Rockstar Mayhem Festival

Who would you like to see play Mayhem, that is realistic. I don't want to see Rammstein, Judas Priest, Metallica, Tool, etc. Which bands would be a lockdown for you to go this year? And, which band (once again realistically) would make you for sure not go?

Usually i go to mayhem as long as there are some good bands there. But for me the worst possible lineup would be like. Avenged Sevenfold, Rob Zombie, Black Veil Brides, Asking Alexandria, and Hollywood Undead. I would for sure go if they got megadeth ,five finger death punch, lamb of god..
