Widely admired for its intricate mathematical construction, the Mayan calendar is far more than just a lightning rod for misguided prophets predicting the end of the world; it is also the source of inspiration for Gravity, the fourth studio recording from the young West Coast-based Empty Cage Quartet.
The album consists of two extended compositions, which are broken into sections and alternated throughout the session. "Gravity" and "Tzolkien" rely on combinations of pitch palindromes and symmetrical harmonic and rhythmic sequences derived from calendar-based number series to yield an endless variety of thematic variations. Despite such meticulous frameworks, the written material is designed to provide additional avenues for group improvisation, which the quartet invests with the same freewheeling enthusiasm that has defined their oeuvre since their inception.
Although "Gravity" and "Tzolkien" may sound like formalist exercises on paper, in practice the quartet brings these labyrinthine pieces to life, investing contrapuntal melodies, cantilevered harmonies and compound meters with unflinching enthusiasm. Using the prescribed structure of each piece as a guide rather than a constraint, they range free and loose, bringing a raw, unfettered sensibility to the proceedings.
Fraught with harsh angles, stop-start rhythms and odd meters, these modular compositions defy simple analysis, yet never sound academic. Mears and Tiner wax opulent harmonies over Johnson and Kikuchi's calibrated undertow, with each member contributing equally to the quartet's intimate four-way conversations. Their approach to each section varies, veering from atmospheric introspection ("Tzolkien 1+13") and pensive pointillism ("Gravity: sections 5-7") to cascading torrents of sound ("Tzolkien 2+9" and "Gravity: section 8"). They draw on multiple traditions, shifting from abstract funk to swaggering bop on "Gravity: section 4," while "Tzolkien 3+6+7" eradicates notions of austerity with its syncopated vamp and lively discourse between Mears' staccato alto and Tiner's muted horn.
Equally informed by complex compositional theory and raw improvisational fervor, Gravity is a compelling example of challenging, yet ultimately accessible creative improvised music. Much has been written about the importance of composition for the future of jazz; this date is an early contender for future case studies.
