Interesting début album by this Texas-based outfit.
The main sound of the band seems to be power metal European style, but with complexities and changes of style and pace that makes prog metal a better description of the music here than power metal. In addition to tunes with complex structures, restrained and melodic vocals, neo-classical guitar soloing and harmony guitar soloing; the last of this seemingly influenced by Iron Maiden; and well thought out use of keyboards to add textures to the songs are central elements of the tunes here. In quite a few tunes slightly arrhythmic riff-patterns is a noticeable element as well.
In style I think this band overall sounds pretty similar to Age of Silence - more complexities in the tunes overall, but style and compositional structures aside this is pretty similar to that band in sound.
Ethereal Architect still lack brilliant songs as I see it, and the production on the album, although adequate as it is, could have been a tad better. Overall a promising début album from what appears to be a talented band.
