::Edited later: I kinda forget why I linked the first one, actually. The second one is them performing it live in 2003. You can hear fairly often Zacky mess up (since he's on lead besides the solo), especially during dual leads. The third one, a 2006 interview, has the following quote: "All the more technical stuff is usually left up to him. I do a lot of the like more galloping, muting stuff, that's more my specialty because that's kinda where I came from with all the punk rock stuff that I always loved writing and stuff. He showed me a lot about lead stuff and I've showed him about stuff about a world that he's not really from."
