Worst voices in metal albums / bands?

Inspired by the current album I'm listening to: Periphery.  Not fond of those growls.

The most recent one I've encountered is Mike Muir from Suicidal Tendencies for his terrible performance on albums like "Join The Army" & "How Will I Laugh Tomorrow When I Can't Even Smile Today".

The Gathering's second album Almost a Dance.

I kinda hated David Wayne's singing on Masterpeace.  On the subject of USPM, how come Mark Shelton decided to let his softer side handle most of Crystal Logic?  It really didn't fit.

I agree. I've never gotten on with "Crystal Logic" & his tone is a contributing factor.

Thorsten "Toto" Bergmann's performance on German speed/thrash metallers Living Death's 1984 debut album "Vengeance of Hell".

Steve "Lips" Kudlow from Anvil in general.

Iron Maiden's Blaze Bayley albums.

I agree. I've never gotten on with "Crystal Logic" & his tone is a contributing factor.

Be careful what you say about Skeletor. He’s know to hold grudges.

Paul Jones sure ruined Enchantment’s otherwise decent Dance the Marble Naked album.

Oh, totally Ben. I was gonna raise that one too.
