If I really want to sync up a YT video that has latency, I'll load it on both my phone and laptop, get em both playing, one with the sound off of course, then hit the spacebar (works as a pause toggle) twice really quick, until they're in sync. haha
But yeah, DAMN good playing! Tight, fast, articulate. Checked all the boxes for me. How long you been playin?
Edit: Ok I just saw in another vid that it's been at least 9 years, lol. To my ears you nailed it back in 2012. I've been using Petrucci's stuff for the last 2 years, getting really serious about my technique in that time, as "lessons", and Fatal Tragedy is a MF bitch!
What do you use to learn the parts? I've found Songsterr to be overall pretty accurate, except for positions.
