Trivium singer/guitarist Matt Heafy has posted a guitar lesson on He writes, "In this lesson, I will be chatting about the fundamentals of rhythm guitar playing; chatting about song-writing, the songs that helped shape my rhythm guitar style and exercise routine, and creating some hybrid-exercise-riffs based off of some Trivium songs." He talks about gear and the importance of listening to many types of music, then goes into exercises based on the songs "Ascendancy" and "Down from the Sky."
