More good signs were apparent in Smuin Ballet’s spring season, which began tonight at Yerba Buena Center for the Arts.  The evening opened with “Swipe,” created last year by the San Francisco Ballet’s Val Caniparoli for the Richmond Ballet in Virginia. Caniparoli excels at making highly technical ballet steps fit organically into a contemporary context, and “Swipe” demands développés extended to dizzying height, allegro footwork, inchworm floor crawls and full-out sprints from its cast of four men and three women.  This followed by an impressive score, a remix of “String Quartet No. 2” by Gabriel Prokofiev (grandson of Sergei), with plucked strings to hypnotic club rhythms and hip-hop beats. Even when there was no recognizable time signature, the dancers hit emphatic notes with spot-on timing.  The dancers moves brought me back to the muscial sounds and dancing experiences from Burning Man 2010!! And lastly, in “Through,” Ma Cong’s sophomore world premiere for Smuin (the first was 2010’s “French Twist”), four couples performed languorous movement to a mashup of often-strident film music by Ryuichi Sakamoto. The dancers performed with clarity and commitment,swapping partners, breaking apart, hiding behind walls and running offstage before any impressions could settle in.  We loved every minute of it!
