yep they are the US Disgorge, and that budybuilder is A.J magana from Consume The Forsaken Album (and he record vocal for Defeated Sanity), you can see to Diego Sanches lead guitar from the original Line-Up of Disgorge, greetings!
So which Disgorge is this? The band whose bassist tragically died? Because I never knew Ron Casey played drums in that one, nor that they had a bodybuilder for a vocalist.
