Call it space rock, call it art rock, call it progressive indie textural mamma jammas. Call it whatever you want, but creating beautiful, challenging, conceptual epics is something that appears to come easy to Boston, MAs Constants. After showing unlimited potential on their 2004 debut, Nostalgia For The Future and its follow-up, 2006s The Murder of Tom Fitzgerril, the band has now firmly and undeniably come into their own on their latest opus. Following their recent split 7" with fellow Bostonians in Caspian, the courageously ambitious three-part exercise in atmosphere and mood on display within The Foundation, The Machine, The Ascension is truly a haunting experience. It knows when to build, when to change, when to climax, when to breathe and when to stop. This is an album of such subtle extremes and tasteful intricacies that the further you delve into its many layers, the more lost you become, and the more rewarded you will be. Not for the faint of heart, this is a music lovers album on every level.
