A box set of further DKV Trio live performances, companion to Past Present. With Drake's cross-rhythms and Kessler's arco-and-pizzicato bass framing Vandermark's reeds, Sound in Motion in Sound captures the long-running Chicago trio in the open-ended 'spontaneous music' that has been its hallmark since 1994 — collective improvisation that stays rooted, however far it ranges, in pulse and swing.
