Airs Tuesday, April 9 at 9 p.m. Yuval Cohen on saxophone, Anat Cohen on reeds and Avishai Cohen on trumpet. They are all siblings from Israel. They're also among the growing number of terrific jazz musicians from that country; Anat and Avishai have both had bookings for their own bands at Newport in recent years. Naturally, the three Cohens occasionally record and perform together as a band, whose original pieces and arrangements are supported by a rhythm section. It's a family reunion you won't secretly dread. They are joined on stage by Reuben Rogers on bass, Rudy Royston on drums and Aaron Goldberg on piano.
