Rockstar Mayhem Festival

slayer was good live when i saw them i saw them at mayhem last year and they were great id say worst band ive seen live is suicide silence they opened up for megadeth their just not that good and it gets annoying

Samael or Veil of Maya

I've seen 3 bands that were just terrible live. Placebo, H.I.M, & A Day To Remember. don't argue it. It was just terrible.

Whitechapel, hands down. Haven't had the misfortune of seeing Rose Funeral yet, who are worse in terms of music, and I've heard terrible things about their live show.

Probably would have to vote for Killswitch at last years Mayhemfest.

Coheed and Cambria! they opened for Slipknot last year and i had to suffer with their terrible music

Static-X? Those guys rock live. I'll agree with Tool. I've seen a million shows and a lot of bad bands, but Tool is worth mentioning. Granted...I'm a metal head who likes pittin to Static-X, Shadows Falls, etc, so Tool isn't up that alley. But I get bored watching Tool. I think their shows are for druggies though...take a hit of acid and or eat some magic mushrooms & it might be a different experience.

being that i like a huge variety of music, ive seen a lot of concerts across many genre's. This fact makes these two bands so bad its embarassing, idk 1 was an opening band " carlotta " gay pop rock band, they didnt gain a single fan that night. Worst signed band, Pop Evil These guys are horrible, saw them open for seether. Then to make matters worst my favorite concert venue booked them as headliners twice within the next 2 months. (i played xbox both nights)

Probably nekromantix on the rob zombie tour last november

Disturbed
