The groove is funky too. For almost eight years, McBride and his bandmates — trumpeter Josh Evans, Marcus Strickland on woodwinds and drummer Nasheet Waits — have been playing exploratory post-bop music without a polyphonic instrument — one that can easily play more than one note at a time — like a piano or a guitar. This makes for a genuinely distinct sound, one that's less dependent on strict harmonic understructures and more creative interplay between instrumentalists.
