It’s a peculiar percolation served up by the wily composer’s mid-sized ensemble. From cello to tuba to guitar, every instrument seems to be playing a percussionist’s role – including the 73-year-old Threadgill. His judicious sax pecking and flute blasts may suggest melody, but they also pepper the action with a lithe forward motion that invariably gooses an oddly fetching groove. Bluster is banished on many of Zooid’s performances, and most of their latest album, the Pulitizer Prize-winning In For a Penny, In For a Pound (Pi Recordings) lets a measured approach signify the music’s sense of intricacy and, ultimately, wisdom. Call it a five-level chess game where the pieces are always in play. The band occasionally rises the roof, and the solos bolster the action, but it’s the crazed propulsion that will be bouncing around your head after the dust has settled on Saturday afternoon at their Newport debut.
