Thing is, it's not an "az", not even close. It's very easy to hear atleast with my sennheisers. Your point could be valid if it actually was an "az", but it isn't. Russell has listed some british metal vocalist as his influences, so I guess it needs to show somewhere. Someone said his assumed "az" sounds unintelligent and brutish or something, but I'd say his vocals sound really damn good and I'm very, very happy that he doesn't try to force any american ARRs in his singing. English is my third language so I can't really give you a proper example, but... "Ö" in my first language is an "oe" sound, like the vowel sound used in "burn". Now pronounce burn without the "r" and just leave the last consonant and you have the british pronunciation (and ö-sound in the middle). Russell clearly says "riders" - "ridöööz", "vindicators" - "vindicatööz". I don't know if that made any sense to you, but that's pretty much the pronunciation I was taught at school. Now, can we quit with this subject cos it's really fucking stupid arguing about something so obvious (if your headphones/speakers don't suck)?
