I like this. It is not your traditional metal, and while I cannot say I love it, there is something rather attractive to it. It brings new sounds into the mix. Their metal is quite traditional, not bad, but not where their true creativity lies. Their ability to mash it up, flip it, fold it in on itself, and use all manner of other sounds to do it makes this sound pretty fresh.
IV is an interesting mix of metal tracks that have had a little work done on them, interspersed with more true dub-style tracks. You have the modified headbangers like "Noise," "Swarm," and "Patient Zero" butting up against the likes of "En Passant," "Ends Justify the Means," and "1.1.:618." there is a battle going on between these two with the end result being the 9-plus minute "Thousand Mile Stare," where everything seems to be coming together.
Dub Trio is an intriguing band. I cannot say they are going on the all time list, but I do like a good portion of what they bring to the table. I may find some of the electronics annoying; seriously some of "En Passant" was just seriously annoying. However, the centerpiece "Ends Justify the Means" is oddly engrossing despite its odd rhythmic progressions. Overall, it is a keeper and recommended for the curious looking for something a little bit different.
