Tricolor are a trio out of Chicago whose members are all over the map musically: guitarist Jeff Parker, an AACM grad, plays with the bands Tortoise (indie rock) and Isotope 217 (Miles-ian jazz/dub/funk fusion); acoustic bassist Tatsu Aoki is active in the Windy City's "free" scene, and recently did a duet album with Malachi Favors; David Pavkovic (drums) plays in various indie rock bands like TOE 2000. The results are fascinating improvs, not easy to "categorize." Parker's style encompasses pre-Mahavishnu John McLaughlin, John Abercrombie and the AACM school of free improvisation. Aoki and Pavkovic play less like a "rhythm section" and more impressionistically (that AACM influence again), splashing dabs of (dark) color on Parker's canvas. If you a "free" jazz fan that sometimes wishes that Derek Bailey would play more "inside" (or if Jim Hall would play "out") or a very adventurous rock fan (i.e., Faust, Can, Dead C, etc.), Mirth + Feckless is worth your time.
