The best thing about this DVD are the interviews. The interviews tell the story of how Mastodon was created and provides a glimpse on how they went from nothing to who they are today. The different performances range from good to bad. Most of the early performances with their original lead singer are awful but it at least helps you see how their sounds has progressed. Standout performances include excellent live versions of Hearts Alive and Megalodon. Would rate this a little higher if the vocals sounded better on most songs but its still a good DVD. More like a 3.8 than 3.5 but not a 4.0.
