Chicago Underground Trio, Chronicle (Delmark). The music is from the trio’s Delmark CD of the same name. The latest expression of the avant garde Chicago cornetist and composer Rob Mazurek, it is alternately explosive and reflective and somehow leaves the listener with a sense of calm. The video by Raymond Salvatore Harmon is muted, layered in shifting pastel splashes and patterns over sequences of Mazurek, percussionist Chad Taylor and bassist Jason Ajemian playing. The visual aspect is as dreamlike as the music.
