Well, re-listening to the Astonishing (this is probably the 3rd time that I've listened to it in full, aside from hearing the songs as their own from time to time,) and it holds up well. I'm approaching Hymn of a Thousand Voices and I'm re-reading the concept of The Astonishing on, yes, Wikipedia and I actually shed a bit of a tear now regarding the whole people in the town coming together and singing which led to Gabriel regaining his ability to sing and bring Faythe back to life.
The power of music is a powerful tool indeed. So, if there's one thing that I'm glad Dream Theater brought with this album, is their ability to tell a story about how great music can be and the obstacles it goes through to be presented in its purest form, but present it in their own way through a fictional story.
