I haven't listened to it yet, but I feel like 17 minutes is going to be more than I need. A 17-minute song of any kind has to be something special. "The Poet and the Pendulum" by Nightwish is 14 minutes long, and that has, like, different acts. It's like seeing a play. Another 3 minutes, it might need an intermission. (I recommend the YouTube vid of the live 2015 performance at Wembley, if you're into symphonic metal. I don't think there's a big drum solo in it, though, so it's not something I'll post here.)
