Six Organs of Admittance - Hexadic (2015)

Hexadic employs a singular, chance-based method of musical composition called the "Hexadic System", developed by Chasny over the last couple years, to create the tonal, rhythmic and lyrical framework on which every track is based. Details on how the system actually works are in short supply (though apparently there's a book forthcoming from Chasny's Drag City label that will explain the whole thing). But suffice it to say that the system uses traditional playing cards to determine the particular set of six notes, called a "hexafield", that can be used for any composition, and that a similarly random, yet highly rule-bound process is involved in the creation of the lyrics.
