Query: Prog Rock is not dead!!

This album is true prog rock and a fantastic album in general.It is destined to be a classic.I fear that about 90% of people that hear it will not understand it, because it is so ahead of its time. At the same time it encorporates classic 70's prog influences, sax, hammond, mellotron, sitar, etc. It will be criminally overlooked for years and then will resurface as one of the best albums of the last 10 years. It is one of those albums that goes over everyones head, but is an absolute must have for any music fan, especially prog heads like myself! If you are reluctant to buy this because of the type of music or image they had in the past, I assure you this is a fresh sound for Sigh.The biggest change is that there are clean vocals on every song, and little or no black metal vocals! Great vocals, very original. In my opinion it is their best album, and will be hard to top, but I hope they continue with this new musical approach. This is a five star album!
