Through September 15 - Jacqueline Kiyomi Gordon: No Touch at Eli Ridgway Gallery. Gordon literally makes audio visible in this show, creating a number of sound installations in the gallery that are simultaneously minimal and maximal. My favorite was Searching for Vespers (LD 1-4), in which speakers in the center of the basement room send out sonic pulses that are deliberately absorbed, reflected, and just plain warped by a quartet of specially-constructed structures set up in a perimeter. Influenced by the theories of Alvin Lucier and Ernst Chladni, Gordon's work is sheer delight to audio nerds but pleasing visually too, as when she creates patterns out of same kind of foam normally used for soundproofing a music studio. Give her pieces some time to work on you, and then wonder how the gallery inhabitants survive with all of those noises going on all day.
