For the Chicago Tribune, Spektral performances are “high-energy thrill rides for musically inquisitive listeners.” A few current projects include a cycle of the complete quartets of Arnold Schoenberg and new commissions by Anna Thorvaldsdottir, David Fulmer and Miguel Zenón. Adventurous and inventive, Spektral partners with the fine pianist Winston Choi, in a pair of back-to-back concerts with two intriguing menus. The first concert continues our Library Late series. It opens with Zorn’s Le Mômo, commissioned by the Library, and two exciting quartets by Wadada Leo Smith and George Lewis. Free admission, reserve tickets online (often available at the door to RUSH patrons).
