Gravity is the new release by the Empty Cage Quartet, a group that The Wire magazine has called “one of the best things in jazz to emerge in the new millennium.” Saxophonist Jason Mears, trumpeter Kris Tiner, bassist Ivan Johnson and percussionist Paul Kikuchi are featured here in one of their most focused and exciting performances on record. The music is comprised of two extended compositions that incorporate improvisational systems based on harmonic palindromes and melodic sequences derived from the cycles of the Mayan calendar. Although these musicians are well-schooled in contemporary and experimental methods of composition, there is nothing overtly intellectual or academic about the musical result. This band is equally at home whether navigating the intricacies of modern chamber music, pounding out a funky groove, or blazing through waves of freebop energy. And they do it all with a bold intensity that is well-honed from years of touring and performing together. This is music that forges a rare union of numerological complexity and visceral groove, brain and guts. And that’s what makes this band so special – their music continues to expand and deepen with each new release, reaching toward, in the words of one critic, an “urban folk music of the future.”
