The name of Dave Rempis’s latest group is fair warning: never before has the local saxophonist led a band that hit this hard. Bassist Anton Hatwich provides a stable fulcrum with his thrumming, insistent vamps, around which drummers Frank Rosaly and Tim Daisy, both on trap sets, play a dynamic array of swinging beats, interlocking Latin motifs, martial cadences, and nuanced, meterless textures. Even at full throttle the two drummers mesh precisely, despite their divergent styles: Rosaly’s is fluid and sinuous, busy with double-kick flutters, while Daisy’s is more spiky and agitated. Rempis sketches keening alto and tenor lines across the surface, taking a more overtly melodic tack than he does in Triage or his free-improv quartet with Jim Baker. At other times he switches to baritone and plunges down into the ensemble’s dense and surging rhythms, using his horn like yet another percussion instrument–and it’s then I start thinking this might be the best new jazz band in town. The set I caught a couple weeks ago at Hotti Biscotti created an unstoppable momentum with its seamless transitions, opening with a polyrhythmic whirlwind worthy of late-60s Pharoah Sanders and building from there. Rempis and company have been gigging hard lately, preparing to go into the studio in late February; they’ll have one more Chicago show before then, at 3030 on the 17th. Tue 2/1, 9:30 PM, Empty Bottle, 1035 N. Western, 773-276-3600 or 800-594-8499, $3.
