As a long time fan, I'm delighted to see these guys pumping out music rivalling the early days. This intro blew me away.
Now excuse me while I listen to this 2h+ masterpiece on repeat for the next month.
Here's a list of the musical motifs I've noticed in this overture:
0:23 Lord Nafaryus
0:44 The X Aspect
1:13 Heaven's Cove
1:46 The fight scene from The Path That Divides
2:28 Faythe's theme (plays several times on the album, but most prominent in Act of Faythe)
2:56 Brother, Can You Hear Me?
3:25 A New Beginning
3:46 A Tempting Offer
4:00 Astonishing
