Nico Nightingale, aka Neud Photo, is no stranger to collaborations. The New Yorker’s latest sees him teaming up with Cristiano F. Grimaldi to form INTRZN, a partnership meshing a free style approach to melodies with cold rhythms. Their “Zone” quartet is a twilight of fluctuating moods. Percussion is bare, allowing bright bars to shine and darker moments to fester. Music which in one breath is elated and uplifting and, the next, dejected and downtrodden.
