Boston-based pianist Sai Ghose has kept his association with bassist Jerry Wilfong and drummer Mike Connors intact over the course of three albums. Their staunch bond can be easily heard throughout their latest release, E-Motion (Summit), which again uses Ghose’s originals as the main frameworks for improvisation. “E-Motion” tweeks the formula a bit by adding saxophonist Sean Berry on four tunes. The additional tonal color brings shading to the project, but the trio tracks stand up just fine thanks to Ghose’s gift for memorable themes and spacious arrangements. He also employs an effective, uncluttered piano style that buffs up such standout tracks as the rhythmically shifting “Only to Depart” and the sprightly ballad “A Clearer Future.” A reimagined “Black Orpheus,” the sole non-Ghose piece, jettisons any languid bossa nova flavor in favor of a brisker pace-a clever device to make use of a beautiful and durable, if overexposed, composition.
