A collective in both genres amassed and sheer body count, Wrekmeister Harmonies has made good on its multifarious ethos. Founder and principal member JR Robinson has enlisted a slew of metal and experimental musicians over his past three records, including Jef Whitehead of Leviathan; Lee Buford and Chip King of The Body; members of Indian, Corrections House and Twilight; and Marissa Nadler, among several others. Robinson's fourth album under the Wrek-Harm name - Light Falls - arguably contains his most high-profile ensemble yet, as he's joined by three members from seminal post-rock pioneers Godspeed You! Black Emperor (Thierry Amar on bass and contrabass; Sophie Trudeau on piano, violin and vocals; and Timothy Herzog on drums). Yet, despite the notability of this trio's inclusion, it's not the most striking feature of Light Falls, an album which changes a crucial aspect of Wrek-Harm's compositional approach up until this point.
