Quartet led by #MichaelZilber, with #OsamEzzeldin #JeffChambers #JeffMarrs, reinterpreting tunes from early #WayneShorter #MilesDavis. This performance was at the California Street Stage located northmost of the festival, a destination as we bypassed multiple other musicians from the south. Explained modal scales to a classically trained musician, puzzling over how an ensemble plays together well.
