It sounds like Dan Swano was involved somewhere (but he's not). Did I mention Costa Rica is where these dudes come from? Really a head scratcher as they clearly display European traits throughout (mostly UK and Sweden). In fact, only half of the band is from Costa Rica (Master Butcher). The other half (Rogga Johansson) lives in Sweden, which could explain the awesome combination.
With this MCD, I have another album that has one huge disappointment, that disappointment is the fact that it ends too soon. Too bad it isn't a full length. I could listen to these guys all day. Reading the bio it mentions bands I don't think they even remotely sound like, trust me it's Bolt Thrower meets early Edge Of Sanity in any comparisons, maybe a touch of Behemoth as well.
