Hyperglyph is the first new album in 11 years from composer / trumpeter / synthesist Rob Mazurek and composer / percussionist Chad Taylor's long-running Chicago Underground Duo project. Mazurek and Taylor have played music together in a multitude of formations over nearly three decades, including their ongoing partnership in Mazurek's large-format-skyward-expressionism vehicle Exploding Star Orchestra, in the expanded Chicago Underground Trio, Quartet and Orchestra (all with guitarist Jeff Parker), as well as a plethora of other assemblages. The early albums by the Duo have proven to be embryonic blueprints for the avant-jazz / electronic / indie rock hybridizing of the time, making them majorly important moments in the articulation of the "jazz" dimensionality of the then-burgeoning "post rock" sound. That sound, of course, was being transmitted far and wide due to the success of these groups as well as the Mazurek/Parker project Isotope 217, and the Chicago Underground's frequently- intersecting collaborators in Tortoise. Just as most of the still-working projects born of that era have evolved, reconfigured, and grown, the Chicago Underground Duo has undergone a number of musical moltings, with the project always in the background of disparate individual aural investigations. The concurrent personal evolutions of Mazurek and Taylor as the Duo project drops off and picks back up makes it a true reflection of their own lives and friendship
