Tufts University Art Galleries invites you to the opening of the exhibition “Impossible Music,” a survey of the sonic vanguard, with a performance of Aki Onda’s installation “Spirits Known and Unknown,” followed by a public reception and community-wide celebration. Organized by curator Candice Hopkins and composer, performer, and installation artist Raven Chacon, “Impossible Music” brings together sculptures, sounds, scores, video, and live performances to explore the radical, interdisciplinary potential of conceptual and experimental music. From the banned to the bombastic, the exhibition highlights the work of visionary artists who pushed music forward, defying norms and piloting new forms of expression. Featured artists include Terry Adkins, Black Quantum Futurism, Nikita Gale, Sarah Hennies, Tom Johnson, Christine Sun Kim, Conlon Nancarrow, Aki Onda, and C. Spencer Yeh.

Aki Onda’s “Spirits Known and Unknown” (45 minutes) is an installation and performance featuring found brass bells that pulls on the myriad association of bells throughout the globe as symbols of spirituality, peace, and even in some cases, war. To mark the opening of “Impossible Music,” Onda developed a score for invited Che Chen and Zach Rowden to perform the bells as a means to ruptures the confines the structures of clock time. “Impossible Music” will be on exhibit through Sunday, April 20.
