Bipolar is a small jazz ensemble consisting of Jed Feuer on trumpet and flugelhorn, Craig Swanson on piano, Stephanie Long on saxophones, flute and piccolo, David Ostrem on bass, and James Windsor-Wells on drums. “Euphrates, Me Jane” is the title track of what I believe is their only CD (2009). To me the group seems to have the knack of sounding as though twice as many people are playing at any one time than there really are.
