PREVIEW In music, silence has a purpose similar to that of the negative space in sculpture: it heightens your awareness of the artist's material. So perhaps for a choreographer as musically adventurous as Liss Fain, it should be no surprise that the two new works in her latest Yerba Buena Center for the Arts concert carry the word "silence" in them. Both pieces are American premieres. At the very least, the two works should offer different perspectives on the concept of stillness. For the first part of Out of the Silence, Fain again turns to the idiosyncratic Gyorgi Ligeti, whose music she used for 2004's Unknown Land, also on this program. She supplements the Ligeti in Silence with music by the Argentinean Osvaldo Golijov, whose cultural roots are also in Eastern Europe. The second local premiere, 2002's Towards the Good Silence (to Bruno Schulz), is a 20-minute duet for Ruth von Mengersen and choreographer Ryszard Kalinowski, both from Poland's Lublin Dance Theatre. (Schulz, who died in 1942, was a solitary writer and graphic artist much admired in Poland). Fain met Kalinowski this summer while her company was touring Eastern Europe and found herself impressed "by his use of narrative as a springboard for physical theater." In her own work she tends toward the abstract and the cool and the incorporation of elegant visual designs. The weekend program is completed by Fain's almost new Resolved, a rethinking of another Steve Reich score from last year.
