Query: Not their best....

I just finishing listening to the album and seeing as how not a single melody is stuck in my head, this is not their best material. This album is a natural progression from Reckoning Night. It's complex, well written and the production is flawless. However, there is not a single fast song on the album. People like me who love "8th Commandment" "The Cage" and "Wildfire" will be disappointed, this is not a power metal album. It is a beautiful piece of work, but will put power metal fans to sleep.
