From my understanding, this song is not usually what Queensryche material sounds like, but it's still epic. I read a comment that described this song as "the closest to Pink Floyd we'll ever get," and I can confirm this. Finally, after a lot procrastination, I finally bought it three months after it was released for Rock Band.
The drums for this song are, obviously, not the main selling point. However, they still stand up pretty well. Absolutely nothing in this song is difficult, save for a single 'lolwtf' roll.
For the most part, slow songs do not cater to drums well, as they have to keep the slow beat. However, the notes you hit are extremely varied. You never play the same pattern for too long, whether it's a basic rock beat with random extra hi-hats, an unusual pattern of several hi-hats followed by a snare or bass, or a much slower version of that beat from Automatic's "Monster".
Still, a slow song is still a slow song, so it's not super exciting or engaging. Plus, there are multiple parts where you play nothing, notably the beginning and ending.
Still, it's definitely a chart you should check out. Plus, from what I've heard vocals and guitar are fantastic as well. Great for those who have all the instruments!
Oh, and apparently 'lucidity' means either the quality of being easily understood or rationality. Thanks dictionary! What would I do without you?
