A fiercely creative composer and improviser, Chicago-born saxophonist Matana Roberts took her artistry to new heights with "Coin Coin Chapter One: Gens de Couleur Libres," an intense and ambitious work that explores her family history with a mix of intense musical expression and spoken word. Recently chosen to perform at England's boundary-pushing All Tomorrow's Parties festival, Roberts will be joined for this performance by Tortoise's Jeff Parker and percussionist Alex Cline. The Edye at the Broad Stage, 1310 11th Street, Santa Monica. Fri., 8 p.m. Free. http://www.18thstreet.org. Reservations available at email@example.com.
