Matana Roberts + Rain Machine + Ryan Sawyer / Nate Wooley / C. Spencer Yeh

Dynamic saxophone conceptualist Matana Roberts continues to focus her formidable creative energy on Coin Coin, her sweeping, multipart narrative epic. In 2013, she issued the work's second chapter, Mississippi Moonchile, a stirring blend of feisty avant-jazz, songful postbop and operatic chant, and here she unveils part three, River Run Thee, a hallucinatory sound collage that features Roberts more as a singer-storyteller than a saxist. She brings this challenging work to the Union Pool stage, with support from Rain Machine, an eccentric art-soul-pop outfit led by TV on the Radio's Kyp Malone, and the formidable experimental-improv trio of drummer Ryan Sawyer, trumpeter Nate Wooley and multi-instrumentalist/vocalist C. Spencer Yeh.
