Got to say, never really expected much out of this song when I first heard it after the announcement, I thought it sounded pretty samey throughout and figured it'd be a pretty weak guitar pick compared to the other two songs in the Roadrunner pack.
Surprisngly it's actually a pretty varied Guitar chart that's fun throughout. The screamo sections have you alt-strumming a pretty unusual string of rapid notes and double strumming throughout, which can be tricky to keep up with as it often changes speed and pacing, but it's easily do-able once you got it down a couple of times. The clean vocals are probably my favourite part of the song though, you get a lot of movement up and down the fretboard once this part kicks in, giving you enough movement to keep you on your feet, but not break a sweat.
After that comes a section with clean and screaming vocals mixed together that requires you to strum a long series of steadily strummed three note chords that change quite often, this is another welcome break too and probably the most relaxed part of the song, it's a good place to wind down and prepare yourself for the solo's.
The first solo is pretty straighforward for the most part with long strings of hammer-ons that take you all over the fretboard, and some quick and fast trill lanes to keep you on our toes. The second solo is a bit more difficult with an insanely fast strumming section that requires you to switch between chords really quickly. This is the hardest part of the song by far, and the toughest to play consistently, but it's over in seconds so for the less experienced player, this won't prove to be much of a barrier, or a fail section.
Overall, this is probably one of the better metal songs you can buy for Guitar, easily the biggest surprise of the week.
