Performers hail from the S.F. Circus School and the well-established New Pickle Circus. The S.F. Circus School, the only one of its kind, attracts students whose levels of ambition range from merely keeping fit to perfecting their professional acts. But many students come specifically to apply themselves to Chinese acrobatics under the demanding eye of trainer Lu Yi, a former performer with the Nanjing Acrobatic Troupe. (Those who've dreamt of running away to the circus but fear death by dismemberment or disaster needn't worry -- as the school's executive director, Patrick Osmond, puts it, "We are not in business to put people at risk.")
In Yu San, students showcase their prowess on the gravity-defying teeterboard, bungie, and the Russian swing. Mixed with these arts will be the more graceful trapeze and aerial hoop performances, and the often underappreciated human contortionist act. Diane Wasnak's famous creation, Pino the Clown, will take her place in the ring, performing the famed backward bicycle ride and other feats of physical comedy and dexterity. Instead of the cacophonous calliope -- that only-at-the-circus organlike instrument whose notes are whistle bursts -- the circus acts will be accompanied by the New Pickle Band, performing an original score by composer Rama Kolesnikow. This week's performances run Wednesday and Thursday at 11 a.m., Friday at 7:30 p.m. (opening night), Saturday at 2 and 7:30 p.m., and Sunday at 2 p.m. (and continue through Jan. 2; call for schedule) at Theater Artaud, 450 Florida (between 17th Street & Mariposa), S.F. Tickets are $10-20; call 621-7797.
