SAY WHAT | Next week, the unutterable: !!!, the dance-punk band from California, rile Portland up with SINKANE, a Brooklyn jazz group. The African folk singer FATOUMATA DIAWARA, from the Ivory Coast via France, performs at the Music Hall in Portsmouth, NH. And three featured in a compendium of Maine poetry — MARTIN STEINGESSER, ROBIN MERRILL, and DAVID MOREAU — lead readings from the volume at Longfellow Books.
