PREVIEW Perhaps the best part of this year's San Francisco International Arts Festival is that it's happening at all. After the dispiriting news of the demise of the Oakland Ballet, one is grateful for anybody who is surviving. SFIAF's dance offerings are not as many as most of us would like, but they are excellent and splendidly varied. The hottest ticket in town, of course, is Sasha Waltz and Guests. The Goethe Institute also includes her work in its concurrent film series. Scott Wells and Dancers are bringing two weekends of sometimes unruly but ever-so-cheeky testosterone-laden work to CounterPULSE, while Jess Curtis/Gravity is leaving its home at CounterPULSE to take a version of its Symmetry Project to Union Square. Curtis and Maria F. Scaroni, in the company of local dancers, will perform their new Transmission. Gravity will appear as part of the free "Jewels in the Square" series, daily noontime performances by local and international dancers throughout the festival. Last, but by no means least, Gamelan Sekar Jaya celebrates its 30th anniversary during the fest. May they have many more and may we have many more SF International Arts Festivals.
