Last year, when Trivium and Dream Theater toured North America together, we sat Matt Heafy and John Petrucci down in our New York offices for an extended conversation about guitar technique, playing style, and much more. We showed you the first three parts on Monday, Tuesday and Wednesday, and now here's the fourth and final part.

Trivium are on the road in the US and Canada again right now, supporting their latest album, In Wavesstop by our tour page to find a show near you! And if you haven't picked up In Waves yet, click here to get your copy!
